libcamera: v4l2_subdevice: Return a unique pointer from fromEntityName()
The fromEntityName() function returns a pointer to a newly allocated
V4L2Subdevice instance, which must be deleted by the caller. This opens
the door to memory leaks. Return a unique pointer instead, which conveys
the API semantics better than a sentence in the documentation.
