[U-Boot] [PATCH] cm5200: fix FAT function prototypes

[Stephen Warren]

Remove FAT function prototypes from the cm5200 firmware update code, and
include the relevant headers instead.

This exposes the fact that the custom prototyoe for do_fat_read() in
this file was incorrect. Rather than simply fixing the call-site, replace
do_fat_read() with fat_exists(). This removes the only use of
do_fat_read() outside of the FAT code.

This should be applied before the series I posted that swaps out the FAT
filesystem implementation for ff.c.
