We're going to have many panels in the kukui family, so I think I'd
prefer it if you moved the compatible string to krane-sku0 dts: it
makes it easier to figure out what's different with sku0.

Then maybe leave all the other properties in this file, as it seems
like all MIPI panels use the exact same pin/supplies?

(And add a comment here saying that the compatible needs to be set in
board dts?)
