moving ata initialisation to a command

[Robert Millan]

I'd like to move ata.mod initialisation away from its _init routine and into
a separate command.  This way it isn't a nuissance when it gets included in
monolithic builds (such as the ones made by grub-mkrescue) and disables biosdisk
completely.

Does that sound fine?
