In the code we do the following in a number of places
to pre-initialize an array with a certain value before
overwriting some of the array with other values:
u8 mainboard_picr_data[FCH_INT_TABLE_SIZE] = {
[0 ... FCH_INT_TABLE_SIZE-1] = 0x1F,
}
clang does not like that behavior unless we specify
the option -Wno-initializer-overrides.
Remove the check for gcc in those places, too, because
1) it would silently change array contents between compilers
2) the check isn't sufficient to determine compilation on
clang vs gcc

Wow, this one is disliked by clang for the empty for() loop, but
looking at the file just makes my eyes bleed a little bit. I remember
the circumstances under which we let this code go in. It was supposed
to save contributions from a vendor, but that never worked out.
Just to keep the little chunks down, here's an indent run and some of
the cruft removed that doesn't actually contribute to functionality in
any way.

In the D0 and D3 ACPI methods use word access to the PME status and
control register. This brings the code inline with the Intel reference
code and matches how the kernel handles access to this register.

For the skylake/kabylake generation of PCH there is an ACPI workaround
for emmc/sd power state that involves disabling and re-enabling dynamic
clock gating after enabling power to the controller, before setting the
power state to D0.
Under certain conditions we have observed that the controller is not
powered and ready by the time the kernel attempts to read the PME
control and status register and so the system will hang while attempting
to read PCI config register 0x84.
To ensure that the controller is ready add a 2ms delay after re-enabling
dynamic clock gating and before setting the power state to D0.
This issue has been observed on eMMC, but the same workaround exists for
the SD card interface so the same delay is added there.
