Looks like no one really knows what this bit would be useful for, nor
when it would need to be set. Especially if coreboot is setting it even
on PCI *Express* bridges. Digging through git history, nearly all
instances of setting it on PCIe bridges comes from i82801gx, for which
no reason was given as to why this would be needed. The other instances
in Intel code seem to have been, unsurprisingly, copy-pasted.
Drop all uses of this definition and rename it to avoid confusion. The
negation in the name could trick people into setting this bit again.
Tested on Asrock B85M Pro4, no visible difference.

According to the ACPI specification, version 6.3:

The same is said about the PM1 Enable registers. Therefore, reporting

All supported x86 chips select HAVE_CF9_RESET, and also use 0xcf9 as

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.

If the PM1b_CNT_BLK is not supported, its pointer contains a value of
