Store the ROM's parent device in each STI struct, so we can associate the STI framebuffer with a device. The new field will eventually replace the fbdev subsystem's info field, which the function fb_is_primary_device() currently requires to detect the firmware's output. By using the device instead of the framebuffer info, a later patch can generalize the helper for use in non-fbdev code.
