ASoC: soc core move card cleanup from soc_remove()

In soc_remove() the card resources are cleaned up.
This can also be done in card_unregister()

This patch move this cleanup into a new function and calls it from
card_unregister. This paves way for further work to allow card registartion
from machine.
