MLK-15071: ASoC: fsl: imx-ak4497: Fix clk for 384KHz and 786KHz (part 2)
With the current multipliers SAI isn't able to derive a correct bitclk.
e.g: When playing at 786Khz with current multiplier
MCLK = 22579200, requested freq 22579200 but SAI wants:
MCLK = (DIV + 1) * 2 * freq [SAI TCR2], so an acceptable solution
is to add a 2x factor to mclk.
