RISC-V SoC drivers for v6.3

Hey Arnd,

I'm sending this one perhaps earlier than needed given there's going to be -rc8 this time around, just in case something about the PMU driver isn't to your liking. It'd be nice if there was a subsystem for these power management units as I wasn't sure if the API usage was correct. Heiko, who has experience from the rockchip driver, reviewed it, so I am happy with that.

Thanks,
Conor.

Merge patch series "JH7110 PMU Support" (2023-01-20 21:57:00 +0000)

----------------------------------------------------------------
RISC-V SoC drivers for v6.3-mw0

It's all StarFive stuff this time:
Their new JH7110 SoC uses a SiFive core complex, and therefore a SiFive cache controller too. That needed a compatible added to both the binding and driver.
The JH7110 also has power domains, which are supported by a new driver and a corresponding dt-binding.
