As far as I know X11 and MIT are similar and MIT is preferred in Linux.
see: LICENSES/preferred.
So I have converted the X11 to MIT but it can be an explicit commit.
This is done implicitly in the Amlogic commit.

Most of the other dts use this style for the header so I would like to
keep this kind of style.
Except if DT maintainers want explicity to move to another style.
Having a coherency in all dts is better and we can move to another
style with a simple script.

Ok, if we agree on the style.

The license expressions in dual licensed files is wrong here, "OR"
should be uppercase.
I can move it to a separate commit if you like.
