irqchip/sunxi-nmi: Const-ify sunxi_sc_nmi_reg_offs structures
The sunxi_sc_nmi_reg_offs, which hold the register offsets for the various variants, is never modified, and only used at init time within the init functions referenced by IRQCHIP_DECLARE, which themselves are tagged __init. Const-ify the sunxi_sc_nmi_reg_offs structures, and tag them as __initconst. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
