If "clocks = <&xxx>" is specified from the CPU or Codec component device node, the clock is not getting enabled. Thus audio playback or capture fails.
Fix this by populating "simple_dai->clk" field when clocks property is specified from device node as well. Also tidy up by re-organising conditional statements of parsing logic.
