.acpi_fill_ssdt() does not need to modify the device structure. This
change makes the struct device * parameter to acpi_fill_ssdt() as
const.

`.read_resources` and `.set_resources` are the only two device
operations that are considered mandatory. Other function pointers
can be left NULL. Having dedicated no-op implementations for the
two mandatory fields should stop the leaking of no-op pointers to
other fields.

Providing an explicit no-op function pointer is only necessary for
`.read_resources` and `.set_resources`. All other device-operation
pointers are optional and can be NULL.

Done with sed and God Lines. Only done for C-like code for now.

These two identifiers were always very confusing. We're not filling and
injecting generators. We are filling SSDTs and injecting into the DSDT.
So drop the `_generator` suffix. Hopefully, this also makes ACPI look a
little less scary.

As discussed on the mailing list and voted upon, the coreboot project
is going to move the majority of copyrights out of the headers and into
an AUTHORS file. This will happen a bit at a time, as we'll be unifying
license headers at the same time.
Updated Authors file is in a separate commit.

Drop 'include <string.h>' when it is not used and
add it when it is missing.
Also extra lines removed, or added just before local includes.

The device tree now supports 'hidden' and the status can be found in
`struct device.hidden`. A new acpi_device_status() will return the
expected setting of STA from a `struct device`.

There's no reason to mutate the struct device when determining
the ACPI name for a device. Adjust the function pointer
signature and the respective implementations to use const
struct device.

Split `i2c.h` into three pieces to ease reuse of the generic defi-
nitions. No code is changed.
* `i2c.h` - keeps the generic definitions
* `i2c_simple.h` - holds the current, limited to one controller driver
per board, devicetree independent I2C interface
* `i2c_bus.h` - will become the devicetree compatible interface for
native I2C (e.g. non-SMBus) controllers

There is a second ACPI _DSD document from the UEFI Forum that details
how _DSD style tables can be nested, creating a tree of similarly
formatted tables. This document is linked from acpi_device.h.
In order to support this the device property interface needs to be
more flexible and build up a tree of properties to write all entries
at once instead of writing each entry as it is generated.
In the end this is a more flexible solution that can support drivers
that need child tables like the DA7219 codec, while only requiring
minor changes to the existing drivers that use the device property
interface.
This was tested on reef (apollolake) and chell (skylake) boards to
ensure that there was no change in the generated SSDT AML.

The Nuvoton NAU8825 audio codec is an I2C device that has a number of
tunable parameters that can be provided to the kernel device driver for
basic configuration and optimal operation.
The configuration options are exposed to devicetree as registers and then
presented as Device Properties via ACPI to the operation system.
This sample configuration in devicetree:
device pci 19.2 on
chip drivers/i2c/nau8825
register "irq" = "IRQ_LEVEL_LOW(GPP_F10_IRQ)"
register "jkdet_enable" = "1"
register "sar_threshold_num" = "2"
register "sar_threshold[0]" = "0x0c"
register "sar_threshold[1]" = "0x1c"
device i2c 1a on end
end
end
Will generate the following code in the SSDT, trimmed for this commit
message as there are more properties that can be configured:
Scope (\_SB.PCI0.I2C4)
{
Name (_HID, "10508825")
Name (_UID, Zero)
Name (_DDN, "Nuvoton NAU8825 Codec")
Method (_STA) { Return (0xF) }
Name (_CRS, ResourceTemplate () {
I2cSerialBus (0x1A, ControllerInitiated, 0x61A80, AddressingMode7Bit,
"\_SB.PCI0.I2C4", 0, ResourceConsumer)
Interrupt (ResourceConsumer, Level, ActiveLow) { 0x3A }
})
Name (_DSD, Package () {
ToUUID ("daffd814-6eba-4d8c-8a91-bc9bff4aa301"),
Package () {
Package () { "nuvoton,jkdet-enable", 1 },
Package () { "nuvoton,sar-threshold-num", 2 },
Package () { "nuvoton,sar-threshold", Package () { 0x0c, 0x1c } }
