For those parts of the arm64 ACPI code that need to check GICC subtables in the MADT, use the new BAD_MADT_GICC_ENTRY macro instead of the previous BAD_MADT_ENTRY. The new macro takes into account differences in the size of the GICC subtable that the old macro did not; this caused failures even though the subtable entries are valid.
