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. Signed-off-by: Gerson Fernando Budke <nandojve@gmail.com>

cpu/atxmega: Add external bus interface Introduce XMEGA EBI driver. This enable EBI for use with all memory supported by the device and peripherals. It include support to SRAM, SDRAM, LCDs or any other external bus access. Note: This feature only works for A1/A1U series, which are, the series with EBI hardware.

cpu/avr8_common: Fix link with binutils > 2.35.2 The xfa.ld script is incompatible with binutils > 2.35.2 and results in firmwares that wont boot. Sadly, I couldn't figure out an elegant way to fix the issue. Instead, I modified the linker script provided by binutils to also include XFA.
