[GIT PULL] irqchip updates for 6.4

[Marc Zyngier]

Thomas,

Here's a small collection of irqchip patches for 6.4. The only
significant thing is the RISC-V IPI rework, which spans both the
irqchip subsystem and the arch code (and is Acked by Palmer).

The rest is a bunch of errata workarounds, fixes and cleanups.

Please pull,

	M.

----------------------------------------------------------------
irqchip changes for 6.4

- Large RISC-V IPI rework to make way for a new interrupt
  architecture

- More Loongarch fixes from Lianmin Lv, fixing issues in the so
  called "dual-bridge" systems.

- Workaround for the nvidia T241 chip that gets confused in
  3 and 4 socket configurations, leading to the GIC
  malfunctionning in some contexts

- Drop support for non-firmware driven GIC configurarations
  now that the old ARM11MP Cavium board is gone

- Workaround for the Rockchip 3588 chip that doesn't
  correctly deal with the shareability attributes.

- Replace uses of of_find_property() with the more appropriate
  of_property_read_bool()

- Make bcm-6345-l1 request its MMIO region

- Add suspend support to the SiFive PLIC

- Drop support for stih415, stih416 and stid127 platforms
