[GIT PULL] irqchip updates for 4.21

[Marc Zyngier]

Thomas,

This is the set of patches I've accumulated during the 4.20
cycle. Although it is larger than some of the previous drops, the
content is relatively straightforward. A few new irqchip drivers
(because life would be boring without them), random fixes, cleanups
and workarounds for stupid firmware implementations.

Please pull.

	M.
