irqchip/gic-v3: Refactor GIC600 limited to 32bit PA erratum handling

Browse source

The GIC600 implementation is now known to be used on multiple 64-bit
SoCs, where it has address width for AXI or APB interface configured
to 32 bit, and it can access only the first 4GiB of physical address
space.

Rework the handling of the quirk to work around this limitation such
that new entries can be added purely as new compatible strings, with
no need to add additional functions or new its_quirk array entries.
