Subject: Remove apparently dead CONFIG_NO_ATA_LEGACY code.


Remove the single snippet of code conditional on the non-existent
CONFIG_NO_ATA_LEGACY Kconfig variable.

i would have mailed a note about this to the ATA maintainer but it
wasn't clear who that was. this is the only dead CONFIG_ variable
under drivers/ata so i figured i'd just submit the patch.

NAK

This option is not dead and is relevant (although the platform using it
may not have the relevant bits merged yet).
