ACPI: processor: Refactor arch_acpi_set_pdc_bits()
The capabilities buffer modified by the arch_acpi_set_pdc_bits() is not
_PDC-specific, as it can be used by _OSC too.
Change the name of that function to better reflect its independence from
_PDC and make it take the capabilities buffer address as the argument
directly, without any offset, as _OSC and _PDC use different capabilities
buffer offsets.
No intentional functional impact.
