When MADT is parsed, print GIC information to make the boot log look pretty:
ACPI: GICC (acpi_id[0x0000] address[00000000e112f000] MPIDR[0x0] enabled) ACPI: GICC (acpi_id[0x0001] address[00000000e112f000] MPIDR[0x1] enabled) ... ACPI: GICC (acpi_id[0x0201] address[00000000e112f000] MPIDR[0x201] enabled)
These information will be very helpful to bring up early systems to see if acpi_id and MPIDR are matched or not as spec defined.
