Support for ATmega328PB

[awatterott]

The latest Atmel toolchain does not support the new ATmega328PB, but the needed files are available from the ATmega Series Device Support (1.0.98).
Can you please add the files (header file, device-specs, avrdude device description) to the next toolchain release?
Here is also an updated header file with the old register/bit naming:

Please include support for the Atmega328PB support going into the releases. This is a very useful chip, it works well, and has some really helpful added capabilities. I especially appreciate having the second Serial channel.

Watterott's contributed changes make the ATmega328PB work very well.

What is the status of this request? I like to start using this chip very soon.

Next toolchain will include 328pb support for sure, alongside 3.6.0 toolchain
