[PATCH v2 11/14] hw/arm: Prefer arm_feature(CBAR*) over object_property_find(reset-cbar)

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

The "reset-cbar" property is added to ARMCPU when the
ARM_FEATURE_CBAR[_RO] features are available. Rather than
checking whether the QOM property is present, directly
check the features.
