The Netgear GS110TPP v1 switch cannot reliably perform cold reboots
using the system's internal reset controller.
On this device, and the other supported Netgear switches, internal GPIO
line 13 is connected to the system's hard reset logic. Expose this GPIO
on all systems to ensure restarts work properly.
