Add Copyright for below Tegra dt-bindings headers:

3. mailbox
4. memory
5. thermal
6. reset
7. pinctrl

Why? Please explain.

These are trivial constants, so I doubt there is here any copyright value.

You may see I was adding the missing Copyright of files created by Nvidia developers in past. I have not evaluated the copyright value of the contents added in the initial check-in. As suggested, I plan to drop this patch in any further revisions of patches from this list.

I am sorry, but that's not entirely how it works. You cannot add only
selected (stripped) copyrights backwards. If adding, please include all
copyright holders.

I had emailed the authors(outside Nvidia) asking about additional Copyright to add, but did not get response from all. One author was fine with adding the Nvidia Copyright. I see now Copyright backwards needs us to follow above approach. As mentioned above in my reply to your comments I am planning to drop this patch if sending subsequent revisions in this patch list.

Thanks for the inputs.
