ASoC: snd_soc_component_driver has snd_compr_ops

Browse Source 
Platform will be replaced into Component in the future.
snd_soc_platform_driver has snd_compr_ops, but snd_soc_component_driver
doesn't have. To prepare for replacing, this patch adds snd_compr_ops on
component driver.

platform will be replaced into component, and its code will be removed.
But during replacing, both platform and component process code exists.
To keep compatibility, to avoid platform NULL access and to avoid
platform/component duplicate operation during replacing process, this
patch has such code. Some of this code will be removed when platform was
removed.
