ide: remove CONFIG_IDEDISK_MULTI_MODE
Use multi PIO by default when available and remove no longer needed CONFIG_IDEDISK_MULTI_MODE (it should be safe nowadays, despite to what help entry has been saying). Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

-config IDEDISK_MULTI_MODE
- bool "Use multiple sector mode for Programmed Input/Output by default"
- help
- This setting is irrelevant for most IDE disks, with direct memory
- access, to which multiple sector mode does not apply. Multiple sector
- mode is a feature of most modern IDE hard drives, permitting the
- transfer of multiple sectors per Programmed Input/Output interrupt,
- rather than the usual one sector per interrupt. When this feature is
- enabled, it can reduce operating system overhead for disk Programmed
- Input/Output. On some systems, it also can increase the data
- throughput of Programmed Input/Output. Some drives, however, seemed
- to run slower with multiple sector mode enabled. Some drives claimed
- to support multiple sector mode, but lost data at some settings.
- Under rare circumstances, such failures could result in massive
- filesystem corruption.

- If you get the following error, try to say Y here:

- hda: set_multmode: status=0x51 { DriveReady SeekComplete Error }
- hda: set_multmode: error=0x04 { DriveStatusError }
-
- If in doubt, say N.
