[PATCH 15/19] drm/msm: 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
lookups.

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