[GIT PULL] irqchip updates for Linux 5.6

[Marc Zyngier]

Hi Thomas,

Here's a bunch of updates from the irqchip dept. On the menu this
time around, three new drivers (SiFive, Aspeed and NXP), a fairly
large update on the GIC side (and it is only the first half, I'm
keeping the juicy bits for 5.7), additional support for the AmLogic
Meson A1 platform, and a bunch of semi-random fixes.

Please pull.

	M.
