ASoC: tegra: Use runtime PM get/put() on SFC device

Browse Source 
SFC driver performs runtime PM operations on the parent device of SFC.
This is not necessary as runtime get/put() calls on the SFC device itself
would be sufficient. Because SFC device is child of AHUB device and
resuming child would resume parent device as well. This does not fix any
functional issue, but just makes code more easy to read.
