Replace 10K power source switchover P-FET pulldown with 1K8 #90

Currently, unless there's a large and low-ESR capacitor in parallel with VSYS, a ZeroPhone might reboot when you unplug the charger. However, swapping the P-FET pulldown resistor from 10K to 1.8K fixes this problem, making the FET open quicker.
