[U-Boot] [PATCH v3.1 01/26] fs: fat: guard the content of include/fat.h

[Akashi, Takahiro]

From: AKASHI Takahiro <takahiro.akashi at linaro.org>

The whole content of include/fat.h should be guarded with CONFIG_FS_FAT.

This is necessary specifically because fs/fs.c unconditionally includes
fat.h, which refers to a config symbol, CONFIG_FS_FAT_MAX_CLUSTSIZE.
So if CONFIG_FS_FAT, and thus CONFIG_FS_FAT_MAX_CLUSTSIZE, is not
defined, fs/fs.c will fail to compile.
