    media: mc: Get media_device directly from pad
    
    [ Upstream commit a967a3a788028f541e4db54beabcebc3648997db ]
    
    Various functions access the media_device from a pad by going through
    the entity the pad belongs to. Remove the level of indirection and get
    the media_device from the pad directly.
