InvisibleSymbol 360b3b578d fix(rak4631): dont touch sx1262 power-enable pin
Upstream Zephyr DTS
[rak4631_nrf52840.dts:124](https://github.com/zephyrproject-rtos/zephyr/blob/c6f781a4988fbb5cc3420f74e36add5ef65dbb94/boards/rakwireless/rak4631/rak4631_nrf52840.dts#L124)
declares P1.05 as `rx-enable-gpios = <&gpio1 5 GPIO_ACTIVE_LOW>`.
MeshCore treats the same pin as `SX126X_POWER_EN`
([variants/rak4631/variant.h:155](https://github.com/meshcore-dev/MeshCore/blob/1a7b3614a8439894714a58af55ab7f501e6bb928/variants/rak4631/variant.h#L155))
and only ever drives it HIGH (= module on,
[RAK4631Board.cpp:51](https://github.com/meshcore-dev/MeshCore/blob/1a7b3614a8439894714a58af55ab7f501e6bb928/variants/rak4631/RAK4631Board.cpp#L51)).
Our driver toggles it per direction at
[sx126x.c:474-475](https://github.com/zephyrproject-rtos/zephyr/blob/684c9e8f32e4373a21098559f748f06915f950c9/drivers/lora/native/sx126x/sx126x.c#L474-L475)
— RX state sets it electrically LOW.

This resulted in degraded rx performance.
