Set Astribank PRI before initialization
This avoids most cases of sending garbage at startup by setting each port
to tristate mode at init time (in the init script) and enable it back at
DAHDI_STARTUO (end of dahdi_cfg).
Upgrade note: if you have upgraded the files (including init script) but old
module is still loaded, you may end up with the port not getting ever
enabled and the line practically dead. In such a case, reload the new module.
