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).

-        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.
