[PATCH/RFC] SATA in its own config menu

[Randy.Dunlap]

From: Randy Dunlap <rdunlap@xxxxxxxxxxxx>

Put SATA into its own menu.  Reason:  using SCSI is an
implementation detail that users need not know about.

Enabling SATA selects SCSI since SATA uses SCSI as a function
library supplier.  It also enables BLK_DEV_SD since that is
what SATA drives look like in Linux.
