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. Aaron Lu, Bob Moore.
