Subject: [PATCH 03/16] media: vimc: Check if the stream is on using ved.stream

Change the way that the subdevices check if the stream is running in set
format functions. It uses the *stream in vimc_deb_device, the more
appropriate pointer. This also makes easier to get rid of the void* and u8*
in the subdevices structs.
