PATCH v3 5/20 video: da8xx-fb: store current display information

From: Afzal Mohammed <[email protected]>

store current videomode and controller data so that reconfiguring can be done easily. Reconfiguring would be required in fb_set_par, which is going to be added soon.

If these details are not stored, the work probe does to retrieve these information would have to repeated at the place of reconfiguring and modifying platform data would be necessary to handle controller data changes like bpp.
