Update the nrf24l01_ioctl function to fully comply with the common wireless character driver interface defined in nuttx/wireless/ioctl.h, and complete previously unimplemented device-specific commands. * Add support for WLIOC_SETRADIOFREQ and WLIOC_GETRADIOFREQ with quantitative conversion between Hz (API) and MHz (Hardware). * Add support for WLIOC_SETTXPOWER, WLIOC_GETTXPOWER, WLIOC_SETFINEPOWER, and WLIOC_GETFINEPOWER. * Add WLIOC_SETMODU and WLIOC_GETMODU, strictly enforcing WLIOC_GFSK modulation as required by the nRF24L01 physical layer. * Map WLIOC_SETADDR and WLIOC_GETADDR to the existing TX address routines. * Resolve -ENOSYS in NRF24L01IOC_GETRETRCFG by reading the NRF24L01_SETUP_RETR register and decoding ARD/ARC shift bits. * Resolve -ENOSYS in NRF24L01IOC_GETDATARATE by parsing RF_DR_LOW and RF_DR_HIGH bits from the NRF24L01_RF_SETUP register.
