drm/i915: Populate fb->format accurately in BIOS FB readout
Use drm_get_format_info() instead of drm_format_info() to populate fb->format during the BIOS FB readout. The difference being that drm_get_format_info() knows about compressed formats whereas drm_format_info() doesn't. This doesn't actually matter in practice since the BIOS FB should never be compressed, but no reason we shouldn't use the more accurate function here anyway.
