drm: Pass pixel_format+modifier directly to drm_get_format_info()

Decouple drm_get_format_info() from struct drm_mode_fb_cmd2 and just
pass the pixel format+modifier combo in by hand.

We may want to use drm_get_format_info() outside of the normal
addfb paths where we won't have a struct drm_mode_fb_cmd2, and
creating a temporary one just for this seems silly.

Done with cocci:
@@
identifier dev, mode_cmd;
@@
struct drm_format_info *
drm_get_format_info(struct drm_device *dev,
- const struct drm_mode_fb_cmd2 *mode_cmd
+ u32 pixel_format, u64 modifier
)
{
<...
(
- mode_cmd->pixel_format
+ pixel_format
|
- mode_cmd->modifier[0]
+ modifier
)
...>
}
