ASoC: tegra: avoid enabling aud_mclk during init

Browse Source 
Enabling the aud_mclk clock during initialization of drivers
was done for T30 chip due to some external dependencies, now
it is not required for latest version of chips and also due
to this aud_mclk is kept always ON. Add check to avoid enabling
aud_mclk clock other than T30
