Here is a first version of a patch.
Cycles count now works with avr910, can't test the others

However, I'm still unsure about a few things.
- I have added a check, so that cycle count isn't tracked, if it can't 
be read before erase. Is this the right thing to do?
- Why is cycle count reset at 0xffff?
- How is the cycle counter protected, when eeprom is written?
