I picked the license identifier of the wm8850.dtsi include, which
defines most of the functionality for this board. No preference from
my side, and happy to use whichever license is common practice for
DTS, but I'm simply not sure how differently licensed files and
includes combine together - thus the conservative choice to stick to
what's already there. The original .dtsi was written by Tony Prisk,
not me.
