Add mmu hwmod data for ducati and tesla.

Please do not use internal codename.
Here again, you completely changed the omap4 existing data for (almost)
nothing.
I agree, the original code was not considering the mmu as a hwmod but
only the core of the subsystem: mmu + cache.
But as far as I can see, you just added a new mmu class, a dev_attr, and
the hwmod remain almost the same.
Otherwise, you replaced the proper names by the bad one, and you removed
important data (hw reset for ex).
Please start from the original code and fix what is missing or wrong but
do not re-write everything.

That change is OK. The remaining part seems to be completely broken.
