arm-bsp: use pre-generated keys instead of haveged in FVP machines

Browse Source 
As the FVP images won't be used in production there is no need to
generate unique SSH keys on the first boot, which takes a long time in a
FVP.

Instead of recommending haveged (from meta-oe) we can simply install
pre-generated SSH keys. These keys are static so should not be used in
production!
