[U-Boot] [PATCH 2/2] Fix cache misalignment after network load operations

After any operation that downloads a file (e.g., pxe get, or dhcp), the
buffer containing the downloaded data is flushed.  This patch rounds
up the flushed size to a cacheline boundary, preventing a cache
misalignment message from u-boot.
