[U-Boot] [PATCH] arm: fix a build error with CONFIG_USE_IRQ

[Masahiro Yamada]

Commit 41623c91 moved exception handling to arch/arm/lib/vectors.S,
breaking CONFIG_USE_IRQ feature.

If CONFIG_USE_IRQ is enabled, undefined reference error occurs.

  arch/arm/lib/built-in.o: In function `interrupt_init':
  arch/arm/lib/interrupts.c:37: undefined reference to `IRQ_STACK_START'
  arch/arm/lib/interrupts.c:37: undefined reference to `FIQ_STACK_START'
  make: *** [u-boot] Error 1

Because arch/arm/lib/vectors.S includes references to
CONFIG_SYS_DV_NOR_BOOT_CFG and CONFIG_USE_IRQ, it must include <config.h>.
