This adds support for setting the flag bits "wrap access disable",
"write allocate override" and "exclusive abort disable" to the L210
variant from the device tree.

The "write allocate override" bit was used on the Nomadik and
necessary to properly make use of the L210 cache on that machine
without sporadic crashes.

I took this oppportunity to add all three flags so we avoid excess
patching for each one.
