Add new option 'sata_mode' to CMOS and 'SATA_MODE' to Kconfig for AMD SB600

coreboot used to set the chipset to IDE mode unconditionally.
Now, the user has a couple of ways to choose the configuration:
- If a CMOS variable sata_mode exist, it is used to decide if IDE or
  AHCI is to be used as interface.
- If not, a Kconfig option is used.
- If unchanged, the Kconfig option is set to IDE.

So unless the cmos.layout is extended or Kconfig is modified, this won't
change behaviour.

[Patrick: Compared to Josef's version, I changed the Kconfig option to
be boolean, instead of a magic string. Also, the "IDE" default is
handled in Kconfig, instead of an additional line of code.]
