[U-Boot] [PATCH 05/11] usb: ehci: Fix aliasing issue in EHCI interrupt code

[Simon Glass]

From: Vincent Palatin <vpalatin at 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.
