[U-Boot] [PATCH] fsl/sata: Replace sprintf() with snprintf()

[Yuantian.Tang at freescale.com]

From: Tang Yuantian <Yuantian.Tang at freescale.com>

Function 'sprintf' does not check buffer boundaries but outputs
to the buffer of fixed size which could cause buffer overflow.
Use a safer function to replace it.
