v7a: at91: add sama5d2-based giant board device tree
The Groboards Giant Board is a ATSAMA5D27C-D1G SiP-based SBC. The board features a 500MHz ARM Cortex-A5 and 128MB DDR2 SDRAM in the SiP as well as a MicroSD slot on the PCB. The device tree is taken from the one in barebox itself based on the vendor's DTS available at https://github.com/Groboards/giantboard-tools Signed-off-by: Ahmad Fatoum <a.fatoum@pengutronix.de>
