Pull irq chip driver updates from Thomas Gleixner:

 - Add support for the Renesas RZ/V2N SoC

 - Add a new driver for the Renesas RZ/[TN]2H SoCs

 - Preserve the register state of the RISCV APLIC interrupt controller
   accross suspend/resume

 - Reinitialize the RISCV IMSIC registers after suspend/resume

 - Make the various Loongson interrupt chip drivers 32/64-bit aware

 - Handle the number of hardware interrupts in the SIFIVE PLIC driver
   correctly

   The hardware interrupt 0 is reserved which resulted in inconsistent
   accounting. That went unnoticed as the off by one is only noticable
   when the number of device interrupts is a multiple of 32

 - The usual device tree updates, cleanups and improvements all over the
   place
