When MADT is parsed, print GIC information to make the boot
log look pretty.

Just reminders.
The acpi_id looks vague, is it a UID for the processor?
Yes, it is the UID of processor object in DSDT, How about use
acpi_uid instead?
Should 0x%08llx for base_address be %p?
Yes, %p should be better, I will update the code and all the
address field you pointed out below.

Same question for base_address.

This block shouldn't be a part of this patch.
Ok, I will remove that from this patch.

Thanks
