NVIDIA: SAUCE: ASoC: Update PLL rate for T264

Browse Source 
The PLLs should be set with a VCO frequency in the 900MHz – 1GHz range
to minimize jitter and ppm error.
Update the PLLA rate accordingly.

Here, 983040000 frequency is for multiple of 8K frequencies
and 993484800 frequency is for multiple of 11.025K frequencies.
