Firstly, you cannot change all of these files in one commit, sorry.

Secondly, we are trying to get rid of selects in arch/riscv at the
moment, not add them. use "default SOC_STARFIVE" in
drivers/reset/kconfig instead please.

I don't think we want to have per soc selection menus in arch code,
I think this should move to drivers/soc (a la Renesas) if you want to
have a per soc selection menu or else just do "default SOC_STARFIVE"
for both clock and pinctrl drivers in the clk and pinctrl Kconfig
entries.

Thanks,
Conor.
