115: Feature/optional pounder r=jordens a=ryan-summers

This PR updates the initialization function to measure the PGOOD output on pounder to detect whether or not pounder is installed.

This also re-enables the high-speed external oscillator for Stabilizer.

**Note**: No timing was conducted on firmware and power-supply management for monitoring PGOOD. It is currently assumed that PGOOD is steady-state before the firmware measures it.
