Michael Ossmann 155a4532f0 HackRF One: swap pins for platform detection
- move EN_1V8 to P5_0, U23 pin 37
- move !VAA_ENABLE to P6_10, U23 pin 100
- move !RX_AMP_PWR back to P2_12, U23 pin 106

Platform detection is now performed using P5_0 and P6_10 which avoids
the complication of having to detect a pull-up to VAA which may not yet
be switched on.
