I wonder if we should not just drop BR2_PACKAGE_RPI_FIRMWARE_INSTALL_DTBS
now the rpi dtbs are now supposed to be in the kernel snce at least 3.19.

Besids, all our rpi defconfig are using the DT from the kernel, which is
another good indication that we don't need those from rpi-firmware
anymore...

If it is not yet in the kernel, it is just a matter of time before it is
available there...
