mpm: n3xx: Don't set time and clock source without dboards

Browse Source 
When there are no daughterboards present, clock and time source are
meaningless. It's also possible that corresponding FPGA images are not
loaded, in which case trying to set those could crash the system. Unless
daughterboards are actually present, these settings won't get applied
any more.
