[ALSA]: Fix sample rate conversion for recording
- Add SRC and convert pin in Standard Input Path.
- Modify the TEGRA_DEFAULT_BUFFER_SIZE to 8KB,
it fixes the breaks in 8bit Mono playback.
- Add S16_BE in supported format to support .au format.
Sample data and other fields are stored in Big endian
form in a-law(au) format.
- Fix review comments on Patch Set 1.
For Bug [LDK/Whistler/ALSA] Attempt to a-law(au)
audio record results application/device hang(9/10).
