[PATCH v2 13/14] hw/arm: Prefer cpu_isar_feature(aa64_mte) over property_find(tag-memory)

[Philippe Mathieu-Daudé]

The "tag-memory" property is added to ARMCPU when the
A64_MTE bit is set in the feature ID register. Rather
than checking whether the QOM property is present, directly
check the feature bit.
