ASoC: rt5659: Update MCLK rate in set_sysclk()

Browse Source 
[ Upstream commit dbf54a9534 ]

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.
