ACPICA: Update FACS waking vector interfaces

Split AcpiSetFirmwareWakingVector into two: one for the 32-bit
vector, another for the 64-bit vector. This is required because the
host OS must setup the wake much differently for each vector (real
vs. protected mode, etc.) and the interface should not be deciding
which vector to use.  Also eliminate the GetFirmwareWakingVector
interface, as it served no purpose (only the firmware reads the
vector, OS only writes the vector.)  ACPICA BZ 731.
