soc/intel/icelake: Use GPIO state macros from intelblocks/gpio_defs.h

TEST=Able to build and boot ICLRVP platform.
1) Dump and disassemble DSDT to ensure GRXS function implementation
remain unchanged prior and after this CL.
2) Verify no ACPI error seen while running 'dmesg' from console.
3) abuild --timeless to ensure there are no other functional changes.
