media: mc: Get media_device directly from pad

Browse Source 
[ 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.
