Commit86e02d0787("media: imx5/6/7: csi: Mark a bound video mux as a CSI mux") made an incorrect assumption that for imx7-media-csi, the bound subdev must always be a CSI mux. On i.MX6UL/i.MX6ULL there is no CSI mux at all, so do not return an error when the entity is not a video mux and assign the IMX_MEDIA_GRP_ID_CSI_MUX group id only when appropriate. This is the same approach as done in imx-media-csi.c and it fixes the csi probe regression on i.MX6UL. Tested on a imx6ull-evk board.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
