avr32: add support for EarthLCD Favr-32 board

This patch adds support for the Favr-32 board made by EarthLCD.

This kit, which is also called ezLCD-101 when running with EarthLCD firmware,
has a 10.4" touch screen LCD panel, 16 MB 32-bit SDRAM, 8 MB parallel flash,
Ethernet, audio out, USB device, SD-card slot, USART and various other
connectors for cennecting stuff to SPI, I2C, GPIO, etc.
