Merge usb changes for Gateworks Cambria boards:
o add support to byte swap EHCI descriptor contents; the IXP435 has dual-EHCI controllers integral but descriptor contents are in big-endian format; this support is configured with the USB_EHCI_BIG_ENDIAN_DESC option and enabled with EHCI_SCFLG_BIGEDESC o clean up EHCI USBMODE register setup during init; add #defines for bit values o split debug support out into a new file and enable use through ddb o while here remove a bunch of lingering netbsd-isms Reviewed by: imp
