Most rpi defconfigs use dtb overlays, but not rpi0 / rpi2 - Making it harder
to use overlays on those boards as the genimage files have to be tweaked.
To fix this, create the rpi-firmware/overlays directory in the post-build
script if needed and unconditionally include it in the genimage files so
rpi0/rpi2 works consistently with the other variants.

Beatify this genimage .cfg file to have consistency with all genimage .cfg
files in Buildroot.

Since release 4.4 a kernel without a trailer is assumed to be device tree
capable. Since our Raspberry Pi defconfigs all use the newer firmware we can
just use the regular kernel image.

Update the raspberrypi and raspberrypi2 configs to use genimage directly
to build the image.
Update the documentation to reflect this, and drop the volatile rootfs
option since it doesn't make much sense and it's not easily integrated
with the genimage configurations.
