[PATCH v2 3/6] ARM: cpu: start: register barebox memory area

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

By registering the barebox area, we ensure that functions like
memory_bank_first_find_space() skip over the memory area barebox uses
for itself.

The OS can still reclaim this area once barebox has shutdown.
