Merge tag 'riscv-jh7110-clk-reset-for-6.4' of https://git.kernel.org/pub/scm/linux/kernel/git/conor/linux into clk-starfive

Pull Starfive clk driver updates from Conor Dooley:

 - Initial JH7110 clk/reset support

A rake of patches, initially worked on by Emil & later picked up by Hal
that add support for the sys/aon clock & reset controllers on StarFive's
JH7110 SoC.

This SoC is largely similar to the existing JH7100, so a bunch of
refactoring is done to share as many bits as possible between the two.
What's here (plus the already applied pinctrl bits) should be sufficient
to boot a basic initramfs.
