[patch] hciattach: added other serial speeds and small help fix.

I spent a couple of hours before understanding that to disable
flow control in H4 modules I needed to put the word "noflow" instead
of just omitting the word "flow" :)

That's why I propose this help change.

Added also other speeds (tested with a csr based module).

Regards,
Diego.
