Pull media updates from Mauro Carvalho Chehab:

 - Removal of several VB1-only deprecated drivers: cpia2, fsl-viu, meye,

 - saa7146 recovered from staging/deprecated. We opted to give ti a
   chance, and, instead of deprecating it, the intention is to write
   patches migrating it from VB1 to VB2.

   planning on dropping it any time soon

 - media controller API has gained experimental support for G_ROUTING
   and streams API. No drivers use it right now. We're planning to add
