[PATCH v5 08/10] media: platform: broadcom: Move unicam driver to subdir

[Jai Luthra]

The BCM283x/BCM2711x SoCs capture camera frames using CSI-2, and
optionally process the raw frames using a VC4 firmware-based ISP block.

As the ISP driver will be added subsequently, move the files related to
the unicam driver to a separate subdirectory to ease distinction between
the two drivers' files.
