ucm: Parse sequence of component devices

Browse source 
A machine device's sequence can enable or disable a component device by
keyword 'enadev' and 'disdev' followed the name of the component device.

UCM sequence parser will find the component device and mark if its enable
or disable sequence is needed by the parent, the machine device.

New element type and struct are defined for the sequence of a component
device. Component devices will be removed from the machine device list
'device_list' of a verb, since we don't want to expose them to audio
servers with original API to list devices for backward compatibility.
A new list 'cmpt_device_list' is used for the component devices of a verb.
