pmc_set_power_failure_state() is usually called twice, once upon boot
(with `target_on == true`) and once from SMM when the system is shut
down (with `target_on == false`). Assuming settings didn't change
between these calls, there is only one case where we actually need
to write the register value: when updating the state for the
MAINBOARD_POWER_STATE_PREVIOUS feature.
This suits us well as we want to avoid unnecessary writes so we
don't clobber the value set upon boot from within SMM. Due to
inaccessible option backends, SMM might not know the current
option state.
The assumption above, that the option value didn't change, may not
be true if the user changed the option on purpose. In the future,
one would have to reboot the machine for option changes to take
effect. However, this doesn't seem to make a huge difference: One
already needed a controlled shutdown for the update to take effect
before. A reboot doesn't seem much more expensive.

APIC Serial Bus pins were removed with ICH5 already, so a choice
'irq_on_fsb = 0' would not take effect. The related register BOOT_CONFIG
0x3 is also not documented since ICH5.
For emulation/qemu-q35 with ICH9 the choice INTERRUPT_ON_APIC_BUS was
wrong and ignored as BOOT_CONFIG register emulation was never implemented.
For ICH4 and earlier, the choice to use FSB can be made based on the
installed CPU model but this is now just hardwired to match P4 CPUs of
aopen/dxplplusu.
For sb/intel/i82371eb register BOOT_CONFIG 0x3 is also not defined
and the only possible operation mode there is APIC Serial Bus, which
requires no configuration.

GDXCBAR and EDRAMBAR are accounted for when reporting resources to the
allocator, but they are not present in the DSDT. In addition, coreboot
does not enable either range, but MRC.bin sets up GDXCBAR and does not
disable it afterwards. Not reporting GDXCBAR in the DSDT can result in
resource conflicts, and not enabling EDRAMBAR can cause issues on CPUs
with eDRAM.
Enable both GDXCBAR and EDRAMBAR in coreboot code, and report these
ranges in the DSDT. This matches what Broadwell does. The value for
the `GDXC_BASE_ADDRESS` macro matches what MRC.bin programs as well.
