[PATCH 03/18] ASoC: cs35l56: cs35l56_component_remove() must clear cs35l56->component

[Richard Fitzgerald]

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().
