OK. Looking through the history log, I saw it different ways, so I was 
not sure.

A while back, I was reading/hearing about how board DT file do not have 
to be GPL and the user should not have to be forced to make this GPL. 
(Maybe at some ELC conference or on LWN or something)
So in our RZ/A BSP that I release to customers I would use this dual 
license. You can see the exact same license in a number of dts files in 
mainline.

Since there is no SPDX for this, I figure Rob might have some opinion on
the matter.
And, if I have to make it GLP for the mainline version, then I will just
replace the license when I release the customer BSP (since I wrote it, 
I can do that). But, I would be nice to keep the BSP version as close to
mainline as I can.
