ASoC: cs35l56: cs35l56_component_remove() must clear cs35l56->component
[ Upstream commit ae861c466ee57e15a29d97629e1c564e3f714a4f ]
The cs35l56->component pointer is used by the suspend-resume handling to
know whether the driver is fully instantiated. This is to prevent it
queuing dsp_work which would result in calling wm_adsp when the driver
is not an instantiated ASoC component. So this pointer must be cleared
by cs35l56_component_remove().
