for KVM_VGIC_V3_ADDR_TYPE_REDIST_REGION attribute, the attribute
data pointed to by kvm_device_attr.addr is a OR of the
redistributor region address and other fields such as the index
of the redistributor region and the number of redistributors the
region can contain.

The existing machine init done notifier framework sets the address
field to the actual address of the device and does not allow to OR
this value with other fields.

This patch extends the KVMDevice struct with a new kda_addr_ormask
member. Its value is passed at registration time and OR'ed with the
resolved address on kvm_arm_set_device_addr().
