Subject: [PATCH] EHCI: Make ehci_qh structure items all 32bit aligned
Intel Moorestown platform EHCI controller has internal SRAM using for
caching of QH/QTD pools, but this SRAM has the 32bit alignment access
limit, all SRAM access must be 32bit aligned. This patch will change
only a few not u32 items to u32.
