        src/sys/dev/usb: ehcireg.h ohcireg.h uhcireg.h

Log Message:
Add the 'volatile' qualifier to all descriptor fields to prevent the
compiler optimising away or reordering accesses to them.

Fixes ehci(4) on NetBSD/evbarm when using -Os optimisation. It's likely
ohci(4) and uhci(4) are similarly afflicted, so the same changes have
been made there.

Quite how other platforms got away without this for so long is a mystery...
