sb/intel/lynxpoint/acpi/lpc.asl: Simplify GPIOBASE resource
LynxPoint-LP handles GPIOs differently, and LynxPoint-H has the same
GPIO kind as previous-generation PCHs, such as Cougar Point. Remove some
unneeded logic from `_CRS` and declare the GPIOBASE resource statically.
The preprocessor allows later ACPI deduplication to remain reproducible.
