ACPICA: Change handling of PM1 Status register ignored bit
Ignored bits must be preserved according to the ACPI spec.
Usually this means a read/modify/write when writing to the
register. However, for status registers, writing a one means
clear the event. Writing a zero means preserve the event (do not
clear.) This behavior is clarified in the ACPI 4.0 spec, and the
ACPICA code now simply always writes a zero to the ignored bit.
