arm: Add has-mpu property
For processors that support MPUs, add a property to de-feature it. This
is similar to the implementation of the EL3 feature.
The processor definition in init sets ARM_FEATURE_MPU if it can support
an MPU. post_init exposes the property, defaulting to true. If cleared
by the instantiator, ARM_FEATURE_MPU is then removed at realize time.
This is to support R profile processors that may or may-not have an MPU
configured.
