ti: am33xx: fix do_enable_clocks() to accept NULL parameters
Up till this commit passing NULL as input parameter was allowed, but not handled properly. When a NULL parameter was passed to the function a data abort was raised. Signed-off-by: Dario Binacchi <dariobin@libero.it> Reviewed-by: Simon Glass <sjg@chromium.org>
