ACPI: processor: Rename ACPI_PDC symbols
The prefix in the names of the ACPI_PDC symbols suggests that they are
only relevant for _PDC, but in fact they can also be used in the _OSC.
Change that prefix to a more generic ACPI_PROC_CAP that will better
reflect the purpose of those symbols as they represent bits in a general
processor capabilities buffer.
Rename pdc_intel.h to proc_cap_intel.h to follow the change of the
symbol name prefix.
No intentional functional impact.
