ACPI: Do not singal PRM support if not enabled
If the OS confirms PRM (Platform Runtime Mechanism) support through the \_SB._OSC PRM bit, the BIOS may start relying on the presence of PRM support in the OS, so prevent the PRM bit from being set in the \_SB._OSC capabilities bitmask when PRM support is not built in so as to avoid confusing the BIOS in that case.
