sb800: sata combine mode configure fix 

Using micro CIMX_OPTION_ENABLED/CIMX_OPTION_DISABLED to
configure SataIdeCombinedMode is wrong.

sbPowerOnInit() use SataIdeCombinedMode to determine whether hide the IDE controller
  0: IDE controller is exposed and Combined Mode is enabled.
     SATA controller has control over Port0 through Port3,
     IDE controller has control over Port4 and Port5
  1: IDE controller is hidden and Combined Mode is disabled,
     SATA controller has full control of all 6 Ports when operating in non-IDE mode
