This helps to use IMFS_make_generic_node() without pulling in the
complete IMFS implementation.

[PATCH 4/5] termios: Use IMFS nodes for new Termios devices
This makes the new Termios devices independent of device major/minor
numbers. It enables BSP independent Termios device drivers which may
reside in the cpukit domain. These drivers require an IMFS and do not
work with the device file system. However, the device file system
should go away in the future.
