drm: Store a pointer to drm_format_info under drm_framebuffer

To avoid having to look up the format information struct every time,
let's just store a pointer to it under drm_framebuffer.

v2: Don't populate the fb->format pointer in drm_framebuffer_init().
instead we'll treat a NULL format as an error later
