	Hi all,

Unlike older GIC variants, the GICv3 DT bindings do not support
specifying a CPU mask in PPI interrupt specifiers.  Hence this patch
series drop all such masks where they are still present.

This has been compile-tested only.  But note that all such masks were
removed before from Renesas SoCs in commit 8b6a006c914aac17 ("arm64:
dts: renesas: Drop specifying the GIC_CPU_MASK_SIMPLE() for GICv3
systems")).

A related question:
The GICv3 DT bindings also support only edge-triggered and
level-triggered PPI interrupts, without specifying polarity.
Apparently, even the common gic_configure_irq() just ignores the
polarity, also on pre-GICv3, so specifying IRQ_TYPE_LEVEL_LOW or
IRQ_TYPE_LEVEL_HIGH doesn't matter at all?
Actual SoC hardware docs (e.g. R-Car Gen4) does document that some
PPI interrupts are active-high, while others are active-low.

Thanks for your comments!
