Guillaume Desmottes 973c6e109a omxvideoenc: factor out enable and disable code
No semantic change, just factor out the code enabling and disabling the
component to their own functions.

Makes the code easier to read as the set_format() method was already
pretty big. Will also allow us to easily change the enabling logic.
