acpi: piix4: remove not needed GPE0 mask
Hardcoded GPE0 mask isn't really needed. Since GPE0_STS initialized
with all bits cleared and only QEMU itself can set bits there (i.e.
guest can only clear bits in it). So guest can't triger SCI
by setting _STS & _EN bits and there is not reason to mask out not
supported _STS bits since they shouldn't be set by QEMU in the first
place.
