[RFC PATCH 1/1] hw/arm: use -cpu max by default for sbsa-ref

[Leif Lindholm]

From: Leif Lindholm <Leif Lindholm quic_llindhol@quicinc.com>

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.
