[PATCH 09/14] ARM: arria10: mark image in OCRAM as valid

[Steffen Trumtrar <s.trumtrar@pengutronix.de>]

The bootrom checks on warm reset if there is already a valid image in
ocram and boots it. Otherwise the next boot slot is loaded.

When barebox gets to this stage, mark it as successfully loaded to ocram.
