* Filter out "default" transfer mode values (0x00 - default PIO mode,
0x01 - default PIO mode w/ IORDY disabled) in write handler for obsoleted
/proc/ide/hd?/settings:current_speed setting.
Allowing "default" transfer mode values is a dangerous thing to do as
we don't support programming controller to the "default" transfer mode
and devices often use different values for the default and maximum PIO
mode (i.e. PIO2 default and PIO4 maximum) so the controller will stay
programmed for higher PIO mode while device will use the lower PIO mode.
There is no functionality loss as by using special IOCTLs device can
still be programmed to "default" transfer modes (it is only useful for
debugging/testing purposes anyway).
* Remove no longer needed IDE_HFLAG_ABUSE_SET_DMA_MODE host flag, it was
previously used by few host drivers to program the controller to PIO0
timings for "default" transfer mode == 0x01 (although some host drivers
