ASoC: rt5640: Update MCLK rate in set_sysclk()

Simple-card/audio-graph-card drivers do not handle MCLK clock when it is specified in the codec device node. The expectation here is that, the codec should actually own up the MCLK clock and do necessary setup in the driver. This is inspired from, commit dbf54a9 ("ASoC: rt5659: Update MCLK rate in set_sysclk()").
