ae3b3ba15c73320f75c121b08266a25a9e5d4edb hw/intc/arm_gicv3: Implement GICv4's new redistributor frame
The GICv4 extends the redistributor register map -- where GICv3
had two 64KB frames per CPU, GICv4 has four frames. Add support
for the extra frame by using a new gicv3_redist_size() function
in the places in the GIC implementation which currently use
a fixed constant size for the redistributor register block.
(Until we implement the extra registers they will RAZ/WI.)
Any board that wants to use a GICv4 will need to also adjust
to handle the different sized redistributor register block;
that will be done separately.
