ASoC: rt5682-sdw: make regmap cache-only in probe

Browse Source 
The RT5682 needs specific attention: there are two regmap in
rt5682_priv struct, one is sdw_regmap which is for IO transfer, and
the other is used for registers control.

We need to set both regmaps when we set cache only. Because if we set
rt5682->sdw_regmap only, rt5682->regmap won't set/get the right value
when it call regmap_write/read(rt5682->sdw_regmap, ...). If we set
rt5682->regmap only, regmap_write(rt5682->sdw_regmap, ...) is used
in rt5682_clock_config which will be called by the ..bus_config ops.
