NetBSD/sys/arch/hpcmips/vr/ite8181_vrip.c
sato 3c83f44fa3 experimental ite8181 video driver for hpcfb.
- just copy from bivideo.
- erase WindowsCE hardware cursor initialy.
- LCD power management codes exist, but currently disabled.
  Because some devices(include ite8181) confuse after LCD power turn on.
  WorkPad z50 power unit seem to be very weak
