548/527 use different TWI port comparing to BF537, update the code to support
user specify a TWI port, usage after change:
1)BF537: twilcd_userspace_test -p 0 -n 0 "8888"
2)BF548: twilcd_userspace_test -p 0 -n 1 "8888"
run twilcd_userspace_test -h for help

OK in bf548-ezkit and bf527-ezkit.
Close it.
