usb-serial: Fix edgeport regression on non-EPiC devices
Fix serious regression on non-EPiC edgeport usb-serial devices. Baud
rate and MCR/LCR registers are not being written on these models due
to apparent copy-n-paste errors introduced with EPiC support.
Failure reported by Nick Pasich <Nick@NickAndBarb.net>.
