intelblocks/acpi: Reserve SBREG BAR/PCH_PRESERVED resource properly

Reserve SBREG BAR if it is outside of the PCH reserved memory range.
Desktop series processors have larger SBREG BARs, which, unlike mobile
processors, do not fall into the standard PCH reserved range
(0xfc800000 - 0xfe7fffff). Special treatment is required if the GPIO
ACPI device is exposed and the GPIO driver claims a part of the SBREG
BAR (or PCH_PRESERVED range depending on SBREG BAR placement). In such
a case the SBREG BAR or PCH_PRESERVED resource has to be fragmented
into pieces, which are not claimed by the GPIO driver. coreboot always
exposes the GPIO device (_STA is hardcoded to 0xF).

Add ACPI methods in SoC-specific gpio.asl files, which return the
ResourceTemplate(s) of SBREG BAR or PCH_PRESERVED resource fragments not
claimed by the GPIO device. Concatenate it with the other resources
reported by MCHC device.
