media: Use designated initializers for all subdev pad ops

Browse Source 
Structures passed to subdev pad operations are all zero-initialized when
declaring variables. In most cases, this is done with designated
initializers to initialize some of the fields to specific values, but in
a minority of cases the structures are zero-initialized by assigning
them to '{ 0 }' or '{ }'.

Improve coding style consistency by using designated initializers where
possible, always initializing the 'which' field.
