Fixes#12816
Commit 42d22f3bdb ({configs/raspberrypi,package/rpi-firmware}: bump
kernel/firmware to 20190819 version) updated the kernel version but failed
to take into consideration that the rpi0w dts file has been renamed:
6f91b5dbfd
Fix it by renaming the dts/dtb file referenced from the kernel build and
genimage.
