[U-Boot] [PATCH 21/28] drivers/fsl-mc: Autoload AOIP image from NOR flash

[York Sun]

From: "J. German Rivera" <German.Rivera at freescale.com>

Load AIOP image from NOR flash into DDR so that the MC firmware
the MC fw can start it at boot time.

Signed-off-by: J. German Rivera <German.Rivera at freescale.com>
Change-Id: I19e23d983e7f947a4398e0421600057e0d7be6a3
[York Sun: This is a debug commit. Will drop once AIOP is loaded by Linux]
