Due to a change in upstream TF-A, boot fails (in edk2) on all cpus that
don't implement FEAT_DIT. The only currently emulated cpu that "supports"
this feature is "max". So switch to using that cpu by default for
sbsa-ref.

However, it is worth noting that the "max" cpu triggers another bug in
TF-A where Linux boot fails around UEFI ExitBootServices.
