gsmd not talking to TI modem on GTA01Bv2

Description

For some reason (probably related to flow control), gsmd doesn't receive the
responses from the GSM modem. Instead, they get buffered inside the modem. If
one uses the 'cu' terminal program after gsmd has terminated, all the pending
responses appear on the terminal.

I will debug this tomorrow, just mentioning it here for the sake of completeness
and documentation.

This actually seems related to the debug board. It short-circuits the serial
line through it's MAX3232.

When using GTA01Bv2 without debug board it works. This is now possible since we
have usbtty in u-boot.
