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.
