Ever since v2.6.19 the code contains a check for CONFIG_NO_ATA_LEGACY.
But that macro has never been defined. Apparently no one ran into
problems on platforms that do not support compatibility mode. So remove
this code that has been dead for over seven years.

Untested!
Perhaps the test should have been
#if !defined(CONFIG_PATA_LEGACY)
I wouldn't know if that's correct. But after seven years it doesn't
matter anyhow, so I did not bother to research that.
