Not able to disable Affinity Routing

I\'m not able to disable the affinity routing (i.e. ARE_S and ARE_NS bits being set always). Reset value of GICD_CTLR register is 0x30.
Actually I want to forward the interrupt from Distributor to multiple Cores but seems to use ITARGETSR, affinity routing should not be enabled.
Can someone please let me know how to do the same ?
