Subject: [RFC][PATCH 3/3] ASoC: wm8940: Do not left shift the div parameter
in wm8940_set_dai_clkdiv
Just check with other codec drivers, we do left shit div for
the corresponding bits from the caller in all other drivers.
I don't find the caller calling wm8940_set_dai_clkdiv now,
just make the behavior consistent with other drivers.
