This driver provides PLL clock registration as well as various clock
branches, e.g. MUX clock, gate clock, divider clock and so on.

PLLs that provide clock to DDR, CPU and peripherals are shown below:

Changes in v2:
- Rewrite clock driver, add platform clock description details in
   clock driver.

  drivers/clk/Kconfig                          |   1 +
  drivers/clk/Makefile                         |   3 +
  drivers/clk/intel/Kconfig                    |  20 ++
  drivers/clk/intel/Makefile                   |   7 +
  drivers/clk/intel/clk-cgu-pll.c              | 166 ++++++++++
  drivers/clk/intel/clk-cgu-pll.h              |  34 ++
  drivers/clk/intel/clk-cgu.c                  | 470 +++++++++++++++++++++++++++
  drivers/clk/intel/clk-cgu.h                  | 259 +++++++++++++++
  drivers/clk/intel/clk-grx500.c               | 168 ++++++++++
  include/dt-bindings/clock/intel,grx500-clk.h |  69 ++++
This belongs with the clk binding patch.

Thanks for review.
Will move it to clock binding patch.
