Not all the paths through the _OSC method returned a value. According
to the ACPI spec (5.0 & 6.0), bit 2 needs to be set for an unrecognized
GUID.
Fixes warnings for both platforms:
dsdt.aml 1143: Method(_OSC,4)
Warning 3115 - ^ Not all control paths return a value (_OSC)
dsdt.aml 1143: Method(_OSC,4)
Warning 3107 - ^ Reserved method must return a value
(Buffer required for _OSC)

It encourages users from writing to the FSF without giving an address.
Linux also prefers to drop that and their checkpatch.pl (that we
imported) looks out for that.
This is the result of util/scripts/no-fsf-addresses.sh with no further
editing.

Replace the AMD SMBus section with the equivalent SB800 smbus.asl
include or remove already commented-out sections.
Verified by running the cpp preprocessor over the DSDTs and diffing the
results against this patch.
The only change is in src/mainboard/siemens/sitemp_g1p1/dsdt.asl, where
someone added RADD and SADD to the OpRegion, but those are unused, so
removing them is fine.

As per discussion with lawyers[tm], it's not a good idea to
shorten the license header too much - not for legal reasons
but because there are tools that look for them, and giving
them a standard pattern simplifies things.
However, we got confirmation that we don't have to update
every file ever added to coreboot whenever the FSF gets a
new lease, but can drop the address instead.
util/kconfig is excluded because that's imported code that
we may want to synchronize every now and then.

Try to 'standardize' the otherwise peculiar method naming to be somewhat
more in-line with other ACPI implementations. This makes it easier to
compare with vendor DSDT dumps for example.

Not all boards which use the AMD cimx/sb800 southbridge have IDE.
However, the southbridge's asl included an 'ide.asl' file which had to
be present in $(mainboard_dir)/acpi.
Address this issue by including ide.asl only in boards which have IDE,
and remove it from all other cimx/sb800 boards.

I am removing the _INI method from the AZHD device because
it does not seem to do anything and causes errors in the
FWTS[1] (Firmware Test Suite) test 'method'. The INI
method performs device specific initialization and is
run when OSPM loads a description table. It must only
access OperationRegions that have been indicated as
available by the _REG (Region) method. We do not have a
_REG method and during my testing, I added a REG method
but it did not seem to make a difference in the PCI
register space. The bit fields defined as NSDI (Disable
No Snoop), NSDO (Disable No Snoop Override), and NSEN
(Enable No Snoop Request) do not ever get written from
their default values. And writing to these bit fields
does not seem to be necessary because I did not notice
any change in audio functionality.
In an effort to clean up as many FWTS errors as possible,
I propose removing this method altogether. I have seen no
change in operation (audio works with and without this
method) and there does not seem to be any change in lspci
or dmesg.
FWTS information can be found here:

Adding the 'WordBusNumber' macro to the PCI0
CRES ResourceTemplate in the Persimmon DSDT.
This sets up the bus number for the PCI0 device
and the secondary bus number in the CRS method.
This change came in response to a 'dmesg' error
which states:
'[FIRMWARE BUG]: ACPI: no secondary bus range in _CRS'
By adding the 'WordBusNumber' macro, ACPI can set
up a valid range for the PCIe downstream busses,
thereby relieving the Linux kernel from "guessing"
the valid range based off _BBN or assuming [0-0xFF].
The Linux kernel code that checks this bus range is
in `drivers/acpi/pci_root.c`. PCI busses can have
up to 256 secondary busses connected to them via
a PCI-PCI bridge. However, these busses do not
have to be sequentially numbered, so leaving out a
section of the range (eg. allowing [0-0x7F]) will
unnecessarily restrict the downstream busses.

change-id I44f22:

The _OSC method is used to tell the OS what capabilities
it can take control over from the firmware. This method
is described in chapter 6.2.9 of the ACPI spec v3.0.
The method takes 4 inputs (UUID, Rev ID, Input Count,
and Capabilities Buffer) and returns a Capabilites
Buffer the same size as the input Buffer. This Buffer
is generally 3 Dwords long consisting of an Errors
Dword, a Supported Capabilities Dword, and a Control
Dword. The OS will request control of certain
capabilities and the firmware must grant or deny control
of those features. We do not want to have control over
anything so let the OS control as much as it can.
The _OSC method is required for PCIe devices and dmesg
checks for its existence and issues an error if it is
not found.

The FrontRunner-AF is a PC/104+ form factor embedded board:
- AMD Fusion G-T56N (1.65 GHz dual core) or T40R (1 GHz single core) APU
- DDR3 SO-DIMM socket (1.5 or 1.35V)
- VGA and LVDS (via Analogix ANX3110)
- AMD A55E (Hudson-E1) southbridge
- 6x USB 2.0
- 1x SATA, 1x CFast socket
- HD Audio (via Realtek ALC886)
- PCI and ISA (via ITE IT8888)
- NEC uPD78F0532 microcontroller on I2C ("SEMA")
- Intel I210 GbE (on APU PCIe x1)
- SMSC SCH3112 SIO
- PS/2
- 2x RS232/485
- 2x SST 25VF032B (SO8, soldered) 4 MB SPI flash (BIOS and failsafe BIOS)

Step 1: copy all files unmodified from Persimmon. This makes it much
easier later to see how the two boards actually and deliberately differ
when porting bugfixes from one to the other. Git's copy detection is
imperfect (and slow).
