driver: video: Migrate from split binaries to single binary firmware

Migrate from mdt way of loading split firmware binaries to single image
file i.e mbn. With firmware memory carved out, there is no benefit of
keeping firmware files as split.
Loading is improved to 6ms with single image binary.
MODULE_FIRMWARE can be introduced with single binary name to provide info
of the firmware associated with video module.
