[PATCH 1/4] ARM: at91: sama5d3: pass BootROM r4 on to barebox proper

[Ahmad Fatoum]

From: Ahmad Fatoum <a.fatoum at barebox.org>

The SAMA5D3 xload entry points pass a literal 0 instead of the BootROM's
r4 to sama5d3_atmci_start_image(). This leads to wrong $bootsource
computation.

Fix this by passing r4 through. Tested on a SAMA5D3 Xplained booting
from SD.
