Thanks for the catch! GENERIC_IRQ_CHIP somehow gets selected by
defconfig, so I didn't see the issue.

Currently we don't need the irq-sunxi-nmi driver, but we may in the
future and it depends on CONFIG_ARCH_SUNXI only, so I guess this patch
is the easiest solution (rather than creating a separate config symbol
for it, which may be an option for later).

So...
