  Mark nssnoc clocks as critical as they are to be turned on to access
nss port tx/rx clocks.

Can you please clarify, if these are turned off, one can not access 
nsscc clocks? Then the nsscc should be the consumer of these clocks 
(instead of declaring them as critical). May be using pm_clk for nsscc 
will work. If not, you'll have to do that manually from 
runtime_suspend/runtime_resume callbacks.
