[PATCH v2 2/2] drm/panel: novatek, nt39016: Remove 'dev' field in priv struct

[Paul Cercueil]

There is already a 'struct device' pointer in the drm_panel structure,
that we can access easily from our priv structure, so there's no need
for a separate 'dev' field there.

v2: Don't initialize drm_panel->dev manually, it is done by
drm_panel_init().
