fc9302465b nb/intel/sandybridge: Refactor get_mem_min_tck
It is not necessary to pass its value around various function calls.
Move it closer to where it is actually used, so as to make it static.
Also, use config_of_soc and flip the branches of the first conditional.

Tested on Asus P8Z77-V LX2, still boots.

2f8ba69b0e Replace DEVICE_NOOP with noop_(set|read)_resources
`.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.

So drop the `_generator` suffix. Hopefully, this also makes ACPI look a

6343cd846a drivers/intel/gma: fold gma.asl into default_brightness_levels.asl
Including gma.asl at the platform level (vs the board level)
means that even desktop boards need to include the default
brightness levels, which makes no sense. To begin to clean this up,
include gma.asl in default_brightness_levels.asl (as well as
the handful of board-specific brightness files) and remove it
from the various platforms.

A follow-on commit will remove default_brightness_levels.asl
from all boards which lack an internal display.

c2e46420cc nb/intel/haswell: Implement proper backlight PWM config
Further backport the backlight-PWM handling from Skylake. Beside
configuring the PWM frequency in Hz, we also use the PCH's logic
for the brightness setting via BLM_PCH_OVERRIDE_ENABLE. Linux
would toggle it anyway and that might confuse our ASL code.

We assume that the 183Hz value that was set before for Slippy
variants was overridden by Linux with the 200Hz VBT value, like
it was for the Broadwell Chromebooks. So we set 200Hz for them
in the devicetrees. The calculated value for the T440p of 220Hz
seems sane and also matches the VBT.

df09bdb726 nb/intel/sandybridge: Rewrite table accessors
There is no need to call get_FRQ a dozen times with the same parameters.
As SNB will eventually use the same code, only IVB is being refactored.

Tested on Asus P8Z77-V LX2, still boots with i7-2600 and i5-3330.

612a867677 drivers/intel/gma/acpi: Add Kconfigs for backlight registers
Instead of adding more versions of the `*pch.asl`, unify the existing
ones and allow to override the register locations via Kconfig. The
current defaults should work for Skylake and some newer platforms.

TEST=Booted ThinkPad X201s, backlight control still works.

a6a64183d6 nb/intel/sandybridge: Void MRC cache if CPUID differs
Native raminit asserts that the DIMMs haven't been replaced before
reusing the saved training data. However, it does not check if the CPU
is still the same, so it can end up happily reusing data from an Ivy
Bridge CPU onto a Sandy Bridge CPU, which runs the raminit_ivy.c code
path. This can make the CPU run in unsupported configurations, which may
result in an unstable system, or a failure to boot.

To prevent that, ensure that the stored CPUID matches the CPUID of the
installed CPU. If they differ, print a message and do not use the saved
data. As it does not pose a problem for a regular boot, but precludes
resuming from S3, use different loglevels depending on the bootpath.

Tested on Asus P8Z77-V LX2 with an i7-2600 and an i5-3330, works well.
