The Device Reset command enables the Host to reset an individual device without
affecting the other device on the same IDE cable. This command shall be accepted
when BSY or DRQ is set to one, DRDY is cleared to 0, or DMARQ is asserted. This
command shall be accepted when in Sleep mode. The command will never end in an
error condition.
