Modified Files:
        src/sys/dev/usb: ehci.c ehcireg.h ehcivar.h

Log Message:
Allocate a whole cacheline for all the descriptor types used by ehci so
that

 i) they can be alloc'ed without USBMALLOC_COHERENT which can mean they're
     now mapped cacheable, and
ii) the "soft" versions are cacheable, and mapped as small as possible.

A quick test of

    dd if=/dev/rsd0 of=/dev/null bs=1m count=1024

improved by approximagely 10% on a Banana PI.
