prod/: P_ON test for atusb can't work as intended ... because we're not in P_ON

Browse Source 
The explanation is simple: reset from any state but P_ON throws us
back into TRX_OFF, not P_ON. That's why the P_ON test only worked
predictably after power-cycling the board.

- prod/atusb (gpio_usb): removed P_ON test
- prod/atben (gpio_ben): added comment to P_ON test explaining why
  it works in this case
