sm501fb: update suspend and resume code
The suspend and resume code is failing to restore the CRT control register, thus causing the CRT data-path to get changed if the SM501 experiences a reset over suspend. Also move some of the debug messages to dev_dbg() level and ensure that the suspend code does not try and restore anything it did not manage to save.
