[media] platform: Make use of media_bus_format enum

In order to have subsytem agnostic media bus format definitions we've
moved media bus definition to include/uapi/linux/media-bus-format.h and
prefixed values with MEDIA_BUS_FMT instead of V4L2_MBUS_FMT.

Reference new definitions in all platform drivers.
