Change dfe-ant-num propert name to dfe-antenna-num.
The change is conde to keep the same naming style
for all properies, like dfe-pdu-antenna property.

Add initialization of GPIOs that are used for antenna switching.
GPIOs provided to DFE extension in Radio peripheral, to drive
antenna switching, should be initialized in GPIO peripheral beforehand.
The initialization is optional and may be disabled by Kconfig.

Add radio peripheral to nrf52833 DTS including antenna matrix
congiuration for Direction Finding extennsion.
Add appropriate binding file for nRF radio peripheral.
There is no default antenna matrix configuration. Antennas number
and GPIOS mapping to DFEGPIOS is project specific.
Complete configuration must be provided by end user as overaly.

Apart from the previously added pins, nRF21540's GPIO interface includes
also MODE pin. This commit adds it to the relevant binding.

The nRF21540 radio front-end-module can optionally be controlled by a
SPI interface. Add a binding and property to link the SPI bus
configuration data to the FEM node.

This device is not an ARM MCU, it's a radio front-end module. Based
on existing Linux practice it belongs in net/wireless.
