None of the currently-supported chips has a GPE1 block. The ACPI spec,
version 6.3, section 4.8.1.6 (General-Purpose Event Registers) says:
If a generic register block is not supported then its respective
block pointer and block length values in the FADT table contain zeros.
Since the FADT struct defaults to zero in coreboot, we don't need to do
anything with GPE1 for now. So, drop the unneeded writes to GPE1 fields.
Tested on Asus P8Z77-V LX2 with Linux 5.7.6 and Windows 10 at the end of
the patch train, both operating systems are able to boot successfully.
