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.
