[U-Boot] [PATCH v9] usb: align buffers at cacheline

This avoids cache-alignment warnings shown in console when a usb command is entered. Whenever X bytes of unaligned buffer is invalidated, arm core invalidates X + Y bytes as per the cache line size and throws these warnings. Signed-off-by: Puneet Saxena --- This patch is tested on "denx-
