Summary

Update 'struct gic_redists' to consolidate all per-cpu redistributor information into a new 'struct redist_pcpu'. Provide a new interface (GICV3_IVAR_REDIST) for the GIC driver which retrieves the above per-cpu data.

This per-cpu redistributor struct will be later used to improve GIC ITS setup.

While there, remove some unused fields in gic_v3_var.h interface.
No functional changes.

If you plan on MFCing this you should keep GICV3_IVAR_REDIST_VADDR to preserve KBI. It can be removed in a later commit that doesn't get an MFC.

I would make GICV3_IVAR_REDIST 1002 with a comment that 1001 was GICV3_IVAR_REDIST_VADDR as it's a change in KBI.
