wireless/nrf24l01: Implement common RF IOCTLs and fix missing register reads.

Browse Source 
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.
