[DistroKit] [PATCH v2 5/7] v7a: at91: add sama5d2-based giant board device tree

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

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
