[U-Boot] [PATCH v3 2/5] usb: ehci: Fix aliasing issue in EHCI interrupt code

From: Vincent Palatin vpalatin@chromium.org

The interrupt endpoint handling code stores the buffer pointer in the QH padding field. We need to make it the size of a pointer to avoid strict aliasing issue with the compiler.
