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 atomiciy
between concurrent operations of clock driver and reset,
power-domain driver that will be introduced in the future.
