new 1645f4ac10 arch/mpfs/usb: Align usb_ctrlreq_s properly to 32-bit
boundary

arch/mpfs/usb: Align usb_ctrlreq_s properly to 32-bit boundary
The alignment of the ctrlreq was correct by luck, and was broken
when the spinlock was added to the structure. In non-smp configurations
spinlock_t is currently 8-bits, causing wrong alignment of the
ctrlreq structure.
