[PATCH v2 07/19] drm/gem: Pass along the format info from .fb_create() to drm_helper_mode_fill_fb_struct()

[Ville Syrjala <ville.syrjala@linux.intel.com>]

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

Pass along the format info from .fb_create() to aliminate the
redundant drm_get_format_info() calls from the gem fb code.

v2: Fix kernel docs (Laurent)
