Log Message:
Revert part of changes in rev 1.298:
 - it breaks cobalt's serial console as mentioned in PR port-cobalt/44292
 - MCR_PRESCALE doesn't affect unless EFR_EFCR is set in the EFR register
 - even if MCR_PRESCALE is enabled we should define appropriate sc_type
   variants and BRG values should be adjusted in comspeed() per sc_type
 - sc_frequency should be adjusted in MD attachment if necessary
Tested on cobalt by several people, ok from jklos@
