Commit 2161536516 ("media: media/pci: set device_caps in struct video_device")
introduced a regression: V4L2_CAP_TUNER is always present in device_caps,
even when the device has no tuner.
This causes a warning:

V4L2_PIX_FMT_NV12 requires num_planes equals to 1,
V4L2_PIX_FMT_NV12M requires num_planes equals to 2.
and mxc-jpeg supports 2 planes for nv12,
so we should use 4L2_PIX_FMT_NV12M instead of V4L2_PIX_FMT_NV12,
otherwise it will confuses gstreamer and prevent encoding and decoding.

The driver allocates and registers two platform device structures during
probe, but the devices were never deregistered on driver unbind.
This results in a use-after-free on driver unbind as the device
structures were allocated using devres and would be freed by driver
core when remove() returns.
Fix this by adding the missing deregistration calls to the remove()
callback and failing probe on registration errors.
Note that the platform device structures must be freed using a proper
release callback to avoid leaking associated resources like device
names.

DST_QUEUE_OFF_BASE is applied to offset/mem_offset on MMAP capture buffers
only for the VIDIOC_QUERYBUF ioctl, while the userspace fields (including
offset/mem_offset) are filled in for VIDIOC_{QUERY,PREPARE,Q,DQ}BUF
ioctls. This leads to differences in the values presented to userspace.
If userspace attempts to mmap the capture buffer directly using values
from DQBUF, it will fail.
Move the code that applies the magic offset into a helper, and call
that helper from all four ioctl entry points.
