[media] au0828: Make the s_reg and g_reg advanced debug calls work against the bridge
The g_reg and s_reg calls worked properly if acting on subdev registers (such as the au8522), but didn't work against the au0828 itself. Copy the logic over from em28xx. Signed-off-by: Devin Heitmueller <dheitmueller@kernellabs.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
