drm/nouveau: fix blank LVDS screen regression on pre-nv50 cards
Commit 2a44e499 ("drm/nouveau/disp: introduce proper init/fini, separate
from create/destroy") started to call display init routines on pre-nv50
hardware on module load. But LVDS init code sets driver state in a way
which prevents modesetting code from operating properly.
nv04_display_init calls nv04_dfp_restore, which sets encoder->last_dpms to
NV_DPMS_CLEARED.
drm_crtc_helper_set_mode
nv04_dfp_prepare
nv04_lvds_dpms(DRM_MODE_DPMS_OFF)
nv04_lvds_dpms checks last_dpms mode (which is NV_DPMS_CLEARED) and wrongly
assumes it's a "powersaving mode", the new one (DRM_MODE_DPMS_OFF) is too,
so it skips calling some crucial lvds scripts.
