The previous code only managed CTX (GPIO 31) — toggling it for TX/RX — but never initialized CSD (GPIO 24) or CPS (GPIO 21), leaving them floating with no pull-up/pull-down resistors on the PCB. With floating CSD and CPS, the SKY66122 was in an undefined operating mode: - The 30 dB TX PA may not have been reliably engaging - The 16 dB RX LNA was never reliably active, degrading receive sensitivity	4 months ago

Fix RAK3401 SKY66122-11 FEM control: enable CSD/CPS for proper PA and LNA operation

The RAK13302 1W module uses a Skyworks SKY66122-11 front-end module with
three digital control pins (CSD, CTX, CPS) that must be actively driven
by the host MCU. The previous code only managed CTX (GPIO 31) — toggling
it for TX/RX — but never initialized CSD (GPIO 24) or CPS (GPIO 21),
leaving them floating with no pull-up/pull-down resistors on the PCB.

With floating CSD and CPS, the SKY66122 was in an undefined operating
mode:
- The 30 dB TX PA may not have been reliably engaging
- The 16 dB RX LNA was never reliably active, degrading receive
sensitivity
