Get rid of ioctl.h for the new CAN drivers

Get rid of ioctl.h for the new CAN drivers

This patch gets rid of include/linux/can/ioctl.h for the new
CAN device interface and drivers. The definitions have been
moved temporarily to include/linux/can/dev.h. Further cleanup
will follow when the bit timing code is updated. The ioctl.h
file has not been deleted, because it's still used by the old
CAN drivers.
