There are 4 GPE0 STS/EN register pairs, each 32 bit wide. However, SoC
code sets a GPE0 block size of 4 byte length instead of 32 byte.
The resulting value of `x_gpe0_blk.bit_with` is wrong, too (32 bit
instead of 256 bit).
Drop the overrides and let common ACPI code set the correct values based
on `GPE0_REG_MAX`.
