Merge contents of structs sun6i_csi and sun6i_csi_dev into a main
sun6i_csi_device structure holding a sun6i_csi_v4l2 struct for things
related to v4l2, as well as the already-existing sun6i_csi_video and
sun6i_csi_config which are left unchanged.
This mostly simplifies accessing stuff by having a single main
structure accessible to every part of the code instead of a private
definition.
No functional change is intended in this commit, variables are just
moved around (cosmetics).
