ARM: 5857/1: ARM: dmabounce: fix build

Commit f74f7e57ae9fa12b2951ae62ce3557799b318399 (ARM: use
flush_kernel_dcache_area() for dmabounce) has broken dmabounce build:

  CC      arch/arm/common/dmabounce.o
arch/arm/common/dmabounce.c: In function 'unmap_single':
arch/arm/common/dmabounce.c:315: error: implicit declaration of function '__cpuc_flush_kernel_dcache_area'
make[2]: *** [arch/arm/common/dmabounce.o] Error 1

Fix it.
