[GIT PULL] irqchip updates for Linux 5.7

[Marc Zyngier]

Hi Thomas,

Here are the irqchip department updates for Linux 5.7.

The largest part is the second half of the GICv4.1 support code (the
*third* half will go via the KVM tree). The rest is a varied bunch of
feature improvement (level trigger support for STM32, multi-instance
support for Xilinx and PLIC, CPU hotplug support for PLIC, Ingenic
X100 support) as well as a selection of fixes (interrupt retriggering,
RPi initialization, a number of GIC blunders...) and cleanups
(farewell to setup_irq).

Stay safe, and please pull,

	M.

The following changes since commit 98d54f81e36ba3bf92172791eba5ca5bd813989b:

  Linux 5.6-rc4 (2020-03-01 16:38:46 -0600)
