[patch, avr] Device macro correction for rev devices

[S, Pitchumani]

Attached patch changes the device name macro of two rev devices, from REV
to rev in the name.

Device name macro:
__AVR_ATmega16HVBREVB__
__AVR_ATmega32HVBREVB__

Change to:
__AVR_ATmega16HVBrevB__
__AVR_ATmega32HVBrevB__

'rev' in small letters emphasizes the revision of the device.

If OK, could someone commit please?

Regards,
Pitchumani
