ACPICA: Resources: Split interrupt share/wake bits into two fields.
These two bits are merged at the external interface level for the
IRQ, Interrupt, and GpioInt resource descriptors. However, these
bits are logically independent and there is no need to keep them
merged internally. Therefore, this change splits the bits into
"sharable" and "wake capable" fields within the resource manager.
This simplifies drive code that needs to examine these bits.
