A semi-large pile of clk driver fixes this time around. Nothing is
touching the core so these fixes are fairly well contained to specific
devices that use these clk drivers.
- Some Allwinner SoC fixes to gracefully handle errors and mark an RTC
clk as critical so that the RTC keeps ticking.
- Fix AXI bus clks and RTC clk design for Microchip PolarFire SoC
driver introduced this cycle. This has some devicetree bits acked by
riscv maintainers. We're fixing it now so that the prior bindings
aren't released in a major kernel version.
- Remove a reset on Microchip PolarFire SoCs that broke when enabling
CONFIG_PM.
- Set a min/max for the Qualcomm graphics clk. This got broken by the
clk rate range patches introduced this cycle.
