This commits add documentation to the AT86RF2xx params and adds generic
exclude patters to the doc check, so that when boards provide custom
AT86RF2xx params they do not need to document them again. The reasoning
is that the documentation in the central place is sufficient.
The ATmega128RFA1 and ATmega256RFR2 contain a version of this IP
on the MCU.
The radio core behaves mostly like a at86rf231, but all registers
are mapped to memory and radio states can directly generate interrupts
on the CPU.
The ATmega256RFR2 adds support for automatic retransmissions.
This has not been implemented yet.
