drm/omap: Pass along the format info from .fb_create() to drm_helper_mode_fill_fb_struct()
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. The patch is based on the driver parts of the patchset at Link: below, which missed converting the omap driver. Due to the absence of this change in the patchset at Link:, after the Fixed: commit below, omap_framebuffer_init() -> drm_helper_mode_fill_fb_struct() set drm_framebuffer::format incorrectly to NULL, which lead to the !fb->format WARN() in drm_framebuffer_init() and causing framebuffer creation to fail. This patch fixes both of these issues. v2: Amend the commit log mentioning the functional issues the patch fixes.
