This change moves all ACPI table support in coreboot currently living
under arch/x86 into common code to make it architecture
independent. ACPI table generation is not really tied to any
architecture and hence it makes sense to move this to its own
directory.
In order to make it easier to review, this change is being split into
multiple CLs. This is change 3/5 which basically is generated by
running the following command:
$ git grep -iIl "arch/acpi" | xargs sed -i 's/arch\/acpi/acpi\/acpi/g'

`.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.

They're listed in AUTHORS and often incorrect anyway, for example:
- What's a "Copyright $year-present"?
- Which incarnation of Google (Inc, LLC, ...) is the current
copyright holder?
- People sometimes have their editor auto-add themselves to files even
though they only deleted stuff
- Or they let the editor automatically update the copyright year,
because why not?
- Who is the copyright holder "The coreboot project Authors"?
- Or "Generated Code"?
Sidestep all these issues by simply not putting these notices in
individual files, let's list all copyright holders in AUTHORS instead
and use the git history to deal with the rest.

RT1011 is a smart amplifier. It needs to know speaker related parameters
including speaker resistor value and temperature when the calibration is
done in order to run Dynamic Speaker Management (DSM) algorithm on chip.
The purpose of DSM is to protect speaker when the volume is large.
The calibration data of speaker is stored in VPD in factory.
This driver is needed to read data from VPD and write to ACPI _DSD when
config CHROMEOS_DSM_CALIB is turned on.
Kernel rt1011 codec driver will read these device properties to set up
codec accordingly on boot.
The reason to prepare these parameters in coreboot is because kernel
codec driver expects to read per-device parameters directly from device
properties. Another benefit is that other OS can also take these
parameters through ACPI _DSD table and take benefit of DSM on RT1011.
The kernel driver device properties of RT1011 are documented at
linux/Documentation/devicetree/bindings/sound/rt1011.txt
It is currently in ASoC maintainer's tree at
https://kernel.googlesource.com/pub/scm/linux/kernel/git/broonie/sound/+/for-next/
and hopefully should be merged to mainline kernel in the next merge window.
BUG=b:140397934
BRANCH=none
TEST=On Helios, with patch series, check realtek,r0_calib and
realtek,temperature_calib are available to rt1011 codec driver.
