avr: Reorder Kconfig entries so that atmega2560 at 16mhz is default 

Reorder the MCU list so that newer chips are at the top of the list.
This causes the very popular atmega2560 to be the default chip
selected.

Reorder the frequency list so that higher frequencies are at the top
of the list.  Restrict the 20Mhz frequency to only chips that support
that speed.  This causes the popular 16Mhz frequency to be the default
speed on AVR.
