ASoC: rt711_*: add snd_soc_component remove callback

[bardliao]

We do some IO operations in the snd_soc_component_set_jack callback
function and snd_soc_component_set_jack() will be called when soc
component is removed. However, we should not access SoundWire registers
when the bus is suspended.
So set regcache_cache_only(regmap, true) to avoid accessing in the
soc component removal process.

@bardliao when device is removing, reg map can be accessed ? Do other drivers implement this ?

regmap can still be accessed during its removing process (device is not removed yet). I didn't see other drivers implement, but I think it is needed for rt711_* codecs. The point is that we can't access sdw registers when the bus driver is suspended. Currently we set regcache_cache_only(regmap, true) in rt711 suspend function. But if we tried to remove sound card in a corner case that codec is in resume but sdw bus is in suspend, we will meet the issue. And set regcache_cache_only(regmap, true) in component remove function can avoid it.
