Merge branch 'riscv-jh7110_initial_dts' into riscv-dt-for-next

Merge Hal's series adding support for the new StarFive JH7110 SoC.
There's a few bindings here for core components that were not picked up
by the various maintainers for the subsystems (previously Palmer would
pick these up via the RISC-V tree) & the first two commits in the branch
are shared with the clk tree, since the dts depends on defines in the
dt-binding headers.

This is based on -rc2, as the board does not actually boot on -rc1
due to the bug Linus introduced.
