cosmetic adaption of drivers/ide/Kconfig concerning SATA

Hello,
since Serial ATA has it's own menu point now, I guess we can change the description of the deprecated SATA driver as well, since the new S-ATA subsystem is not configured through a SCSI low-level driver anymore.

The following patch is against 2.6.21-rc3:

There are two drivers for Serial ATA controllers.

- The main driver, "libata", exists inside the SCSI subsystem
+ The main driver, "libata", exists in the "Serial ATA subsystem"
and supports most modern SATA controllers.

The IDE driver (which you are currently configuring) supports

Since I am not subscribed to the list, I'd find it great if I were personally CC'ed. :-)

Best regards
