Subject: [PATCH] arm64/sunxi: 4.6-rc1: Add dependency on generic irq chip

Commit ce3dd55b99b1 ("arm64: Introduce Allwinner SoC config option"),
added support for ARCH_SUNXI on arm64, but failed to select
GENERIC_IRQ_CHIP, which is required for drivers/irqchip/irq-sunxi-nmi.c
and causes build failures like :

  UPD     include/generated/compile.h
  CC      init/version.o
  LD      init/built-in.o
drivers/built-in.o: In function `sunxi_sc_nmi_set_type':
