[PATCH v2 13/19] drm/i915: Pass along the format info from .fb_create() to drm_helper_mode_fill_fb_struct()

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Plumb the format info from .fb_create() all the way to
drm_helper_mode_fill_fb_struct() to avoid the redundant
lookup.

For the fbdev case a manual drm_get_format_info() lookup
is needed.
