[GIT PULL] irqchip updates for 5.13

[Marc Zyngier]

Thomas,

This is the set of irqchip/irqdomain updates for 5.13. Only a couple
of new drivers this time around (though see below for the actual
truth), a handful of fixes, and the start of a long overdue cleanup of
the irqdomain library to try and get rid of some of the ancient (and
mostly unused) cruft.

But this PR isn't the full story: we also have support for the Apple
M1 going via the the arm-soc tree, as it made more sense to keep all
the various bits together. There is also the MSI rework to get rid of
the msi_controller abstraction that is going via the PCI tree.

Please pull,

	M.

The following changes since commit 5fbecd2389f48e1415799c63130d0cdce1cf3f60:

----------------------------------------------------------------
irqchip updates for Linux 5.13

New HW support:

- New driver for the Nuvoton WPCM450 interrupt controller
- New driver for the IDT 79rc3243x interrupt controller
- Add support for interrupt trigger configuration to the MStar irqchip
- Add more external interrupt support to the STM32 irqchip
- Add new compatible strings for QCOM SC7280 to the qcom-pdc binding

Fixes and cleanups:

- Drop irq_create_strict_mappings() and irq_create_identity_mapping()
  from the irqdomain API, with cleanups in a couple of drivers
- Fix nested NMI issue with spurious interrupts on GICv3
- Don't allow GICv4.1 vSGIs when the CPU doesn't support them
