ASoC:tegra-alt: Add alsa ctls to set SFC o/p rates

Browse Source 
This change will add the alsa controls to set
SFC i/o rates. SFC from 44.1 to 48 Khz is validated
using this change.

Find below the list of added alsa controls :-
1)"SFC# output rate"
2)"codec-x rate"

'#' = 1,2,3,4 for the respective SFC used.

Bug 200090046
