ARM: GIC: function to retrieve the physical address of the SGIR In order to have early assembly code signal other CPUs in the system, we need to get the physical address for the SGIR register used to send IPIs. Because the register will be used with a precomputed CPU interface ID number, there is no need for any locking in the assembly code where this register is written to.
