[Taniya Das]

 [v4]
  * Add comments for the RCGs/CBCRs using the CLK_GET_RATE_NOCACHE flag.

 [v3]
  * Move frequency table macro to common file,
    add the patch along to maintain dependency.

 [v2]
  * Removed unused header file includes.
  * Moved the frequency table macro to a common file [1].
  * Move to pll config to probe.
  * Update SoC name in device tree binding and
    also update the Kconfig.

Add support for the display clock controller found on SDM845
based devices. This would allow display drivers to probe and
control their clocks.
