The Heltec Wireless Tracker and its UC6580 doesn't support a soft sleep, so we hard sleep it. It was discovered that this causes the gnss chip to lose its settings. This means the buffer overflows with NMEA messages we don't use, and constellations that were previously enabled may be disabled. This patch attempts to fix it by performing the configuration of the UC6580 chip every time it comes back from hardsleep. Fixes meshtastic#5088
