We want to allow the psci-conduit property to be set after realize, because the parts of the code which are best placed to decide if it's OK to enable QEMU's builtin PSCI emulation (the board code and the arm_load_kernel() function are distant from the code which creates and realizes CPUs (typically inside an SoC object's init and realize method) and run afterwards. Since the DEFINE_PROP_* macros don't have support for creating properties which can be changed after realize, change the property to be created with object_property_add_uint32_ptr(), which is what we already use in this function for creating settable-after-realize properties like init-svtor and init-nsvtor. Note that it doesn't conceptually make sense to change the setting of the property after the machine has been completely initialized, beacuse this would mean that the behaviour of the machine when first started would differ from its behaviour when the system is subsequently reset. (It would also require the underlying state to be migrated, which we don't do.)
