commit 92a18a657fb2e2ffbfa0659af32cc18fd2346516 upstream.

Sierra Wireless EM7565 devices use the QCSERIAL_SWI layout for their serial ports

but need sendsetup = true for the NMEA port to make it work properly.

Simplify the patch compared to v1 as suggested by Bjørn Mork by taking advantage of the fact that existing devices work with sendsetup = true too.

Use sendsetup = true for the NMEA interface of QCSERIAL_SWI and add DEVICE_SWI entries for the EM7565 PID 0x9091 and the EM7565 QDL PID 0x9090.

Tests with several MC73xx/MC74xx/MC77xx devices have been performed in order to verify backward compatibility.
