Hi All,

This patch series adds support for indicating MOD clocks as no PM (if any). 
Patch#1 adds DEF_NO_PM() macro to flagup no PM clock and patch #2 switches
sysclk and vclk clocks to no PM.

Sending it as an RFC as there wasn't any way we could obtain the priv data
due to which I had to create a static global var for rzg2l_cpg_priv.

RFC->v1
* Added no_pm_mod_clks and num_no_pm_mod_clks members as part of
  struct rzg2l_cpg_priv so that we dont loop the entire mod clocks
  array for each device probe.
* Patch#2 unchanged

Cheers,
Prabhakar
