irqchip: mips-gic: Use HW IDs for VPE_OTHER_ADDR

Browse source

The Linux CPU number doesn't necessarily match up with the ID used for a
VP by hardware. Convert the CPU number to the HW ID using mips_cm_vp_id
when writing to the VP(E)_OTHER_ADDR register in order to ensure that we
correctly access registers for the VPs of secondary cores. This most
notably affects systems using CM3, such as those based around I6400.
