[GIT PULL] irqchip updates for 5.5

[Marc Zyngier]

Hi Thomas,

Here's a large-ish irqchip update targetting 5.5.

The bulk of the changes this time are the QC PDC wakeup support that
has been brewing for longer than I care to remember, a bunch of GICv3
cleanups in preparation for the GICv4.1 code (which is 5.6 material),
a bunch of GICv4 fixes (which owe a lot to Zenghui's careful review
of the v4.1 patches), Broadcom wakeup support and a driver for
a FSL/NXP platform.

The rest is a bunch of DT updates, cleanups, fixes and other cosmetic
changes.

Please pull.

	M.
