On PCH-H the I2C4 0:19.0 device isn't usable and thus 0:19.1 and
0:19.2 can't be detected using standard PCI probing.
Remove I2C4, I2C5 and UART2 from generic ASL code on PCH-H platforms
that advertise its PCI conformance by the _ADR attribute.

According to the ACPI specification, version 6.3:
Accesses to the PM1 status registers are done through byte or word
accesses.
The same is said about the PM1 Enable registers. Therefore, reporting
dword-sized access is wrong and means nothing anyway. Since some other
platforms use word-sized access, use word everywhere for consistency.

All supported x86 chips select HAVE_CF9_RESET, and also use 0xcf9 as
reset register in FADT. How unsurprising. We might as well use that
information to automatically fill in the FADT accordingly. So, do it.
To avoid having x86-specific code under arch-agnostic `acpi/`, create a
new optional `arch_fill_fadt` function, and override it for x86 systems.

Instead, just flip the desired bits using bitwise operations. As this is
initially zero, the resulting value is the same. This allows flags to be

Both `acpi_fill_fadt` and `soc_fill_fadt` set many FADT fields. Since
the latter runs later, the values programmed in it overwrite any other
values. Drop unused assignments and consolidate everything in a single
function. Use `acpi_fill_fadt` as it is mandatory (no weak definition).

This register block is optional, if not supported its block pointer and

Since the FADT struct defaults to zero in coreboot, we don't need to do
anything to indicate PM2_CNT is not supported. So, drop unneeded values.
Also delete a comment about `pm2_cnt_len`, which said that the right
value differs from zero. Looks like that comment was wrong instead.
