ASoC: tegra: Enable/Disable parent runtime pm

Browse Source 
Instead of using duplicate clock of "d_audio" for all AHUB modules
get/put runtime pm reference of the parent module from runtime_pm
suspend/resume routine of all AHUB modules. This will ensure AHUB
xbar is up before other drivers tries to access any register. Also
it will ensure both d_audio and APE clocks are enabled when needed.
