USB: remove ancient/broken CRIS hcd
Remove the old crisv10 HCD ... it can't have built for some time, doesn't even have a Kconfig entry, was the last driver not to have been converted to the "hcd" framework, and considering the usbcore changes since its last patch was merged, has just got to buggy as all get-out. I'm told Axis has a new driver, and will be submitting it soon.
