ASoC: tegra: Fix redundant PLLA and PLLA_OUT0 updates 
Tegra audio graph card has many DAI links which connects internal
AHUB modules and external audio codecs. Since these are DPCM links,
hw_params() call in the machine driver happens for each connected
BE link and PLLA is updated every time. This is not really needed
for all links as only I/O link DAIs derive respective clocks from
PLLA_OUT0 and thus from PLLA. Hence add checks to limit the clock
updates to DAIs over I/O links.

This found to be fixing a DMIC clock discrepancy which is suspected
to happen because of back to back quick PLLA and PLLA_OUT0 rate
updates. This was observed on Jetson TX2 platform where DMIC clock
ended up with unexpected value.
