clk: spacemit: Add clock support for SpacemiT K1 SoC

The clock tree of K1 SoC contains three main types of clock hardware (PLL/DDN/MIX) and has control registers split into several multifunction devices: APBS (PLLs), MPMU, APBC and APMU. All register operations are done through regmap to ensure atomicity between concurrent operations of clock driver and reset, power-domain driver that will be introduced in the future.
