[PATCH] nfit: Fix undefined mmio_flush_range on x86_32

From: Toshi Kani
Date: Fri Aug 28 2015 - 21:20:59 EST

The following compile error was observed on x86_32 since nfit.c
relies on <asm/pmem.h> to include <asm/cacheflush.h>, which only
works when CONFIG_ARCH_HAS_PMEM_API is set on x86_64.

drivers/acpi/nfit.c:1085:5: error: implicit declaration of
function 'mmio_flush_range' [-Werror=implicit-function-declaration]

Change nfit.c to include <asm/cacheflush.h> directly for now.

Apply on top of libnvdimm-for-next of the nvdimm tree.
This is a temporary fix and please feel free to replace it with
a better solution.
