MLK-15071: ASoC: fsl: imx-ak5558: Fix clk for 384KHz and 786KHz
With the current multipliers SAI isn't able to derive a correct bitclk.
e.g: When recording at 786Khz with current multiplier
MCLK = 24576000, requested freq 24576000 but SAI wants:
MCLK = (DIV + 1) * 2 * freq [SAI TCR2], so an acceptable solution
is to add a 2x factor to mclk.
