On OMAP platforms (like OMAP5) Linux kernel fails to detect a SATA device if it is used by U-Boot.
It happens because U-Boot does not reset SATA controller before boot.
Reset the controller on OS boot so that Linux will have a clean state to work with.

To be clear, since we're using CMD_SCSI and not CMD_SATA is why we need this reset sequence here instead of the sata_stop() that say i.MX uses.
