Merge the mode-init functions of ofdrm and simpledrm to the new helper
drm_sysfb_mode(). Also implement the DPI defaults there. Replace the
code in each driver with the shared helper.

Add struct drm_sysfb_device that stores the system display's hardware
settings. Further helpers for the mode-setting pipeline will use these
fields. Convert ofdrm and simpledrm by embedding the sysfb device in
their device structs.

The ofdrm and simpledrm drivers are special as they operate on
externally provided framebuffers. Move them into their own sub-
directory. Will let them share common code.
