Ian Lepore 7c2136adbb Add option USB_HOST_ALIGN to configs that contain 'device usb'. Setting
this to the cache line size is required to avoid data corruption on armv4
and armv5, and improves performance on armv6, in both cases by avoiding
partial cacheline flushes for USB IO.

All these configs already exist in 10-stable.  A few that don't (and
thus can't be MFC'd yet) will be committed separately.
