The clock controller generates clocks for the whole chip, including
system clocks and all peripheral clocks. This driver support ma35d1
clock gating, divider, and individual PLL configuration.

There are 6 PLLs in ma35d1 SoC:
- CA-PLL for the two Cortex-A35 CPU clock
- SYS-PLL for system bus, which comes from the companion MCU
and cannot be programmed by clock controller.
- DDR-PLL for DDR
- EPLL for GMAC and GFX, Display, and VDEC IPs.
- VPLL for video output pixel clock
- APLL for SDHC, I2S audio, and other IPs.
CA-PLL has only one operation mode.
DDR-PLL, EPLL, VPLL, and APLL are advanced PLLs which have 3
operation modes: integer mode, fraction mode, and spread specturm mode.

Hi Jacky,

Since I have already picked up the previous version of this patch,
