  chips/atmega: Make EEPROM size target-specific. Add sync eeprom

328p has 1024 bytes of eeprom, 1284 and 2560 have 4096 bytes. Devices
missing xon/xoff support need synchronous put support where the target
sends a CR every 16 bytes and the host waits for that. This avoids
overrunning the serial input buffer.

with the specified address The address is left-justified with the LSB
read-bit set to zero.

 5. Button
 6. Rotary Potentiometer
 7. Air Pressure
 8. 3-Axis Acceleration

Still to add:

 1. OLED display
 2. Temperature and Humidity

Of course, the ROM is full at this point, so adding these presents a
significant challenge.
