ACPI: tables: Print CORE_PIC information when MADT is parsed
When MADT is parsed, print CORE_PIC information as below:
ACPI: CORE PIC (processor_id[0x00] core_id[0x00] enabled)
ACPI: CORE PIC (processor_id[0x01] core_id[0x01] enabled)
...
ACPI: CORE PIC (processor_id[0xff] core_id[0xff] enabled)
This debug information will be very helpful to bring up early systems to
see if processor_id and core_id are matched or not as spec defined.
