ASoC: Introduce 'fixup_controls' card method
The new method is called just before the card is registered, providing
an opportune time for machine-level drivers to do some final controls
amending: deactivating individual controls or obtaining control
references for later use.

Some controls can be created by DAPM after 'late_probe' has been called,
hence the need for this new method.
