ASoC: mediatek: mt8188: correct etdm control return value

Browse source 
In mt8188_etdm_clk_src_sel_put() function, val retrieved by FIELD_PREP
is shifted to the corresponding bit filed, so it can compare with the
register value directly.

Originally, the redundant bit shift of the register value results in
the wrong comparison result, so we remove bit shift operation in the
patch.
