Hey Stephen, (and Philipp if you want I guess?),

Here's a PR for the StarFive JH7110 clk/reset bits since I'd like to
take the DT this cycle & depend on the binding headers.

I've picked up R-B tags from Emil on all that patches, despite him being
listed as an author, as things have changed quite a lot since he was
involved in writing things many months ago.

The base here is -rc2 rather than -rc1 as -rc1 has issues booting on
this platform. Please pull and all that lark..

Cheers,
Conor.

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.
