irqchip updates for 6.2

- More APCI fixes and improvements for the LoongArch architecture,
  adding support for the HTVEC irqchip, suspend-resume, and some
  PCI INTx workarounds

- Initial DT support for LoongArch. I'm not even kidding.

- Support for the MTK CIRQv2, a minor deviation from the original version

- Error handling fixes for wpcm450, GIC...

- BE detection for a FSL controller

- Declare the Sifive PLIC as wake-up agnostic

- Simplify fishing out the device data for the ST irqchip

- Mark some data structures as __initconst in the apple-aic driver

- Switch over from strtobool to kstrtobool

- COMPILE_TEST fixes
Merge branch irq/misc-6.2 into irq/irqchip-next
