ASoC: Intel: sof_sdw: Allocate snd_soc_card dynamically
The static card_sof_sdw struct is modified during runtime and in case the
module is not removed, but the card is, then the next time the card is
created the card_sof_sdw will contain information from the previous card
which might lead to hard to debug issues, side effects.
Move the snd_soc_card into mc_private and use that to make sure that the
card is initialized correctly.
