SERIAL: omap: simplify

We have the sequence:
	- LCR mode B
	- write EFR with ECB clear
	- LCR mode normal
	- if s/w flow
		- LCR mode B
		- write EFR with ECB clear
		...
		- LCR mode B
		- write EFR with ECB clear
		- LCR mode normal

This can be simplified to:
	- if s/w flow
		- LCR mode B
		- write EFR with ECB clear
		...
	- LCR mode B
	- write EFR with ECB clear
	- LCR mode normal
