I'm marking this series as RFC for now, as the driver is based on vendor code,
and only tested on FPGA, the production SoC chip isn't ready yet.

The SpacemiT K3 SoC's CCU (clock control unit) is similar to old K1 generation,
the clock and reset functionalities are distributed across several IP blocks,
therefore, we model them as several clock tree accordingly.

The PLL clocks has changed register setting layout, so introduce a PLLA type.
Some gate clocks has inverted enable/disable logic which writing 1 to disable,
while writing 0 to enable.
