Add an explicit rf-switch-mode devicetree property for LLCC68 instances, covering no switch handling, TXEN/RXEN complementary GPIO control, and DIO2 single-pin control for PE4259-style RF switches. Preserve the existing default behavior with an auto Kconfig default that only enables complementary GPIO handling when both TXEN and RXEN GPIOs are present. Resolve the RF switch mode into llcc68_config at build time and validate incompatible devicetree combinations with BUILD_ASSERT checks. Configure optional RXEN GPIO handling for DIO2 single-pin mode and keep DIO2 RF switch control disabled unless that mode is selected. Replace the old fire-and-forget TX/RX GPIO helper with a result-returning mode-aware RF switch state helper, and apply it across standby, sleep, CAD, TX, RX, continuous wave, infinite preamble, and modem init paths. Add SetRxDutyCycle support with explicit raw 24-bit LLCC68 period units, plus helpers and a millisecond wrapper for callers that work in time units. Select the RX RF path before issuing the duty-cycle command so RXEN stays valid for duty-cycle listen windows.
