[Intel-gfx] [PATCH] drm/i915/sdvo: fix panel_type initialization

[Jani Nikula]

Commit 3f9ffce5765d ("drm/i915: Do panel VBT init early if the VBT
declares an explicit panel type") started using -1 as the value for
unset panel_type. It gets initialized in intel_panel_init_alloc(), but
the SDVO code never calls it.

Call intel_panel_init_alloc() to initialize the panel, including the
panel_type.
