ACPICA: Optimize ACPI register locking
Removed locking for reads from the ACPI bit registers in PM1
Status, Enable, Control, and PM2 Control. The lock is not required
when reading the single-bit registers. The acpi_get_register_unlocked
function is no longer needed and has been removed. This will
improve performance for reads on these registers. ACPICA BZ 760.
