Orchard EVT1 to DVT1
ECO1: Fix Microphone mirroring
Microphone schematic symbol was mirrored. No BOM change, board layout change only.
ECO2: Make battery easier and safer to solder
Space battery terminals wider, increase pad size, and add solder mask openings around the battery tabs. This makes it less likely to short wires together during a botched soldering operation.
ECO3: Fix gas gauge topology
Gas gauge goes between the charger and battery, not between the charger and the system. Oops!
