87f7e5a963 cpu/atmega_common: move clock init to common code
This code should not be in the realm of the board config, but in
common arch code.

93ed3cd9d6 cpu/atxmega: Add periph power management
The current xmega don't have a way to disable peripherals that are
not in used.  Add peripheral management to allow enable only the mcu
blocks that will be used by application.  This saves power on active
and sleep modes.  By default, at clock initialization, all peripherals
are now disabled and each drive must activate at initialization phase.
The periph_timer and periph_uart were updated with this new feature.

1a88f0bad6 cpu: Introduce Atmel xmega cpu
Add ATxmega common files and cpu definitions.

This works was originally developed by @Josar.  The 2018 version
were port to 2021 mainline.

This version changes original port to have only the atxmega CPU
definition. With that, all family can be accomodated.
