Revisiting the start/stop sequence used by the tlv320dac33 codec in
order to avoid race conditions, which can occur, when the codec is in
FIFO modes.
It has been found that OMAP3 McBSP needs the BCLK continuously running
on the serial interface when it is configured to be slave.
DAC33 can be configured in a way, that it keeps the BCLK ticking, and
only enable the FS when it is needed.
Option for the platform data to select between continuous BCLK or non
continuous BCLK.

  ASoC: tlv320dac33: Start/stop sequence change
  ASoC: tlv320dac33: Add option for keeping the BCLK running
