arm-bsp/linux-yocto: Enable virtio-rng for fvp-baser-aemv8r64

Browse Source 
A virtio-rng is available from FVP_BaseR_AEMv8R version 11.17, so add
to the device tree and enable the correpsonding FVP configuration flag.

This improves the boot time and removes the following warning in the
boot log:

    random: udevd: uninitialized urandom read (16 bytes read)
