Add the AM33xx RNG module's device tree data.
Also add Documentation file describing the data
for the RNG module.

Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com>
---
Changes since V1:
- Drop "status=disabled" entry in dt node, Since
  RNG is present on all AM33xx platforms.

Seems you missed this patch. Please consider this for this merge window.
Patch 2/2 is already taken by Paul.
Without this patch AM335x boot will crash as I mentioned in my cover letter.

Thanks and regards,

I do not see the acked-by for the binding part. You do need that for any 
new bindings nowadays.

It looks good to me, but it does not apply on my branch.
Please rebase it and repost with the proper acked-by.

OK enough of waiting here, I'm picking this patch into
omap-for-v3.13/dt branch as it removes some boot time warnings
we're seeing.
