[v3,0/3] riscv: canaan: Add support for K230-Canmv clock

Message

This patch series adds clock controller support for the Canaan Kendryte
K230 SoC. The K230 SoC includes an external 24MHz OSC and 4 internal
PLLs, with the controller managing these sources and their derived clocks.

The clock tree and hardware-specific definition can be found in the
vendor's DTS [1],
and this series is based on the K230 initial series [2].
