ACPICA: Add function to handle PM1 control registers
Added acpi_hw_write_pm1_control. This function writes both of the PM1
control registers (A/B). These registers are different than than
the PM1 A/B status and enable registers in that different values
can be written to the A/B registers. Most notably, the SLP_TYP
bits can be different, as per the values returned from the _Sx
predefined methods.
