[U-Boot] [PATCH] fat: Define MAX_CLUSTSIZE only if not defined in config

[Michal Simek]

From: Siva Durga Prasad Paladugu <siva.durga.paladugu at xilinx.com>

Define MAX_CLUSTSIZE only if not defined in board specific
config file as this size can be decreased to save memory
in some memory constrained cases.
