This breaks the usage of mainline kernel as there is no -revc1 suffix
in the wandboard dtb files there.

linux-wandboard needs to rename the dts files like mainline does:

imx6q-wandboard.dtb (for rev C1)
imx6q-wandboard-revb1.dtb
imx6dl-wandboard.dtb  (for rev C1)
imx6dl-wandboard-revb1.dtb

If they can't rename their dts, then they would need to carry this
patch on their own U-Boot tree.
