module_adapter: Extend the module interface 

Add the bind/unbind ops that can be optionally implemented by modules to
perform module-specific actions when other modules are bound/unbound
from them.

These are particularly useful for modules such as the mixers, smart_amp,
copier that can have multiple input/output pins.
