[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).
