[PATCH] ide: pdc202xx_old: remove the obsolete busproc
Remove the busproc from pdc202xx_old.c because:
- it handles the obsolete HDIO_TRISTATE_HWIF ioctl instead of the modern
HDIO_SET_BUSSTATE, so treats its argument wrong;
- I don't think that tristating both channels is good idea (probably can't
be done otherwise since there seems to be only single bit controlling this).
