Instead of validating the links to capture devices and subdevices with the same function, use the default v4l function for links between subdevices and only use a different function for validating between capture device and subdevice. This change should also ease future work to associate multiple mbus codes for the same pixelformat in vimc_pix_map.

The kernel driver never touches the decoded buffers with the CPU. All accesses are either done by hardware DMA masters or userspace mapping the buffers. This means we don't need a kernel virtual address mapping for those buffers at all. As those buffers are usually quite large, we can save a good deal of kernel vmalloc space by requesting to not have a kernel mapping set up for them.

The BIT decoder picture run temporarily locks the bitstream mutex while the coda device mutex is locked, to refill the bitstream ring buffer. Consequently, the decoder start command, which locks both mutexes when flushing the bitstream ring buffer, must lock the coda device mutex first as well, to avoid an ABBA deadlock.
