ACPI: Work around IASL warning reading/writing same register
The newer versions of IASL are unhappy when an operator
has the same object as both source and destination.
The warning can be completely disabled with a command
line argument, but in general, I'd really rather not
just disable warnings.
The bits in this register are write 1 to clear, so reading and
writing the same register is what we want to do. Instead, store
it in a temporary register then write it in a second operation.
Fixes warning:
dsdt.aml 1396: Store(PWST, PWST)
Warning 3023 - ^ Duplicate value in list
(Source is the same as Target)
