Jacob Dahl 565fa806ff hwdef: ARK_FPV: expose 12V POWER AUX output as a relay
The 12V output on the POWER AUX connector is gated by a BEC enable on
PG4. It was driven on at boot with no way to control it, and the enable
was mislabeled VDD_5V_PERIPH_EN even though it drives the 12V rail, not
5V.

Rename it to VDD_12V_PERIPH_EN, give it a GPIO, and pre-map it to RELAY1
via RELAY1_PIN_DEFAULT so it can be switched from an RC channel
(RELAY1_FUNCTION + RCx_OPTION). Default behavior is unchanged: the rail
is still on at boot via the pin's OUTPUT HIGH state.
