[PATCH v3 1/4] irqchip: armada-370-xp: re-order register definitions

In order to clarify to which register base the various register
definitions apply, this commit re-orders them, and adds a comment that
clearly indicate which registers are relative to "main_int_base" and
which registers are relative to "per_cpu_int_base".
