drm/i915/dsi: switch to drm_panel interface
Replace intel_dsi_device and intel_dsi_dev_ops with drm_panel and
drm_panel_funcs. They are adequate for what we have now, and if we end
up needing more than this we should improve drm_panel. This will keep us
better aligned with the drm core infrastructure.
The panel driver initialization changes a bit. It still remains hideous,
but fixing that is beyond the scope here.
v2: extend mode config mutex to cover drm_panel_get_modes (Shobhit)
vbt_panel->intel_dsi = intel_dsi in vbt panel init (Shobhit)
