Subject[PATCH] hpt366 fix
Another one in the IDE series.

The HPT366 code is broken - it tries to set the interface
to a too high speed, which leads to error messages at boot
time and/or to data corruption.

The typical effect at boot time is

<4>hde: set_drive_speed_status: status=0x51 { DriveReady SeekComplete Error }
<4>hde: set_drive_speed_status: error=0x04 { DriveStatusError }

This is fixed by the patch below.
