[PATCH 06/14] media: rockchip: cif: store endpoint information in private data

[Michael Riesch]

The endpoint information such as bus width or flags are required
to set CIF (and on certain variants GRF) registers correctly. Store
the information in the private data of the driver in order to make
it accessible.
