ASoC: imx-card: Fix DSD/PDM mclk frequency

[ Upstream commit c0fabd12a8570cb932f13d9388f3d887ad44369b ]

The DSD/PDM rate not only DSD64/128/256/512, which are the
multiple rate of 44.1kHz,  but also support the multiple
rate of 8kHz, so can't force all mclk frequency to be
22579200Hz, need to assign the frequency according to
rate.
