ASoC: tlv320dac33: Internal clocking changes
During validation of the internal clocking setup it has
been found that the following settings were not configured
in an optimal way:
ASRC_CTRL_A: SRCLKDIV was incorrect, instad of divide ratio 3,
ratio of 2 has to be used (as the comment stated)
DAC_CTRL_A: Fs = Fsref is the desired configuration instead of
Fs = Fsref / 1.5
