Enable the ARM_FEATURE_EL2 bit on Cortex-A52 and Cortex-A57, since this is all now sufficiently implemented to work with the GICv3. We provide the usual CPU property to disable it for backwards compatibility with the older virt boards. In this commit, we disable the EL2 feature on the virt and ZynpMP boards, so there is no overall effect. Another commit will expose a board-level property to allow the user to enable EL2. Backports commit c25bd18a04c8bd0f19556d719864b7b08528222d from qemu
