On OMAP platforms (like OMAP5) Linux kernel fails to detect a SATA

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.
You are right, sata_stop() can be used here.
Unfortunately, OMAP SATA access is implemented via SCSI, so I managed to
implement this workaround.

Dmitry
