[PATCH 3/5] arch/arm: mioa701 add IPL and DPS1 updater

[Robert Jarzmik <robert.jarzmik@free.fr>]

In order for barebox to be functional, the docg3 DPS1 has to
protect barebox from writes, and have its embedded IPL coded
to load barebox (as barebox is the SPL).

Add a raw DPS1, which :
 - protects the area from block 6 to block 123
   This is DPS1 + barebox + barebox-logo
 - encodes the 2048 bytes IPL
