src: Report byte-sized access for GPE0

According to the ACPI specification, version 6.3:

    OSPM accesses GPE registers through byte
    accesses (regardless of their length).

So, reporting dword-sized access is wrong and means nothing anyway.

Tested on Asus P8Z77-V LX2, Windows 10 still boots.
