src: Report word-sized access for PM1a_EVT
According to the ACPI specification, version 6.3:
Accesses to the PM1 status registers are done through byte or word
accesses.
The same is said about the PM1 Enable registers. Therefore, reporting
dword-sized access is wrong and means nothing anyway. Since some other
platforms use word-sized access, use word everywhere for consistency.
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.
