MMIO operations are arch-agnostic so the include

PCI config accessors are no longer indirectly included
from <arch/io.h> use <device/pci_ops.h> instead.

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.

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.

Remove the bit of code that was putting the SerialIO devices into
D3Hot state when they are switched from PCI to ACPI mode. Instead,
add the appropriate ACPI Methods to allow the kernel to control the
power state of the device.
The problem seems to be that if the device is put in D3Hot state
before it is switched from PCI to ACPI mode then it does not properly
export its PCI configuration space and cannot be woken back up.
Adding the ACPI Methods for _PS0/_PS3 allows the kernel to transition
the device into D0 state only when it is necessary to communicate with
the device, then put it back into D3Hot state.

The clock gating register at offset 0x800 is managed by the
clock driver in the kernel when the devices are in ACPI mode.
When in PCI mode we should force enable the clock here.
When in ACPI mode or the device is disabled it should be put
in D3Hot state.

This adds configuration of SerialIO devices in the Lynxpoint-LP
chipset. This includes DMA, I2C, SPI, UART, and SDIO controllers.
There is assorted magic setup necessary for the devices and
while it is similar for each device there are subtle differences
in some register settings.
These devices must be put into "ACPI Mode" in order to take
advantage of S0ix. When in ACPI mode the allocated PCI BARs
must be passed to ACPI so it can be relayed to the OS. When
the devices are in ACPI mode BAR0+BAR1 is saved into ACPI NVS
and then updated and returned when the OS calls _CRS.
Note that is is not entirely complete yet. We need to update
the IASL compiler in our build environment to support ACPI 5.0
in order to be able to pass the FixedDMA entries to the kernel.
There are also no ACPI methods defined yet to do D0->D3->D0
transitions for actually entering/exiting S0ix states.
This is hard to test right now because our kernel does not support
any of these devices in ACPI mode. I was able to build and test
the upstream bleeding-edge branch of the linux-pm git tree. With
that tree I was able to enumerate and load the driver for the
DesignWare I2C driver and attempt to probe the I2C bus -- although
there are no devices attatched.
I am also able to see the resources from ACPI in /proc/iomem get
reserved properly in the kernel.
