ASoC: da7213: Extend support for the MCK in range [2, 50] MHz

According to DA7212 HW manual, the codec's PLL input divider can operate
with MCLK range from 2MHz to 50MHz but current driver only set the
minimum supported MCLK frequency to 5MHz. That cause 11.025kHz audio
which is corresponding to MCLK of 2.8224MHz (11.025kHz * 256) unable to
play in case audio-simple-card is used.
