While refactoring the way the ITSs are probed, the handling of
quirks applicable to ACPI-based platforms was lost. As a result,
systems such as HIP07 lose their GICv4 functionnality, and some
other may even fail to boot, unless they are configured to boot
with DT.
Move the enabling of quirks into its_probe_one(), making it
common to all firmware implementations.
