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.

The snd_pcm_hw_params struct is pretty large (604 bytes) and keeping two local copies of it can make the stack frame really large. It is worth noting the variables are in separate code blocks so for some optimisation levels in the compiler these will get automatically combined keeping the stack frame reasonable. But better to manually combine them to cover all cases. Add a single local variable for __soc_pcm_hw_params and use in both loops to shrink the stack frame.
