Add initial support for the ATmega128RFR2 which according to Atmel is a
drop in replacement for the ATmega128RFA1 however in real world testing
I have found this to not be entirely true. All of the changes (new
features) added to the R2 are not exposed with current simavr
peripherals so this file is identical to the A1 in simavr.
