sb/intel/lynxpoint: Remove incomplete SATA ACPI code
The existing SATA ACPI code for Lynx Point implements some methods and
devices, but not completely. These methods are optional and only used in
IDE mode. The code was likely copied from bd82x6x, where it has since
been removed.
As a result, many remarks produced by iasl about unreferenced objects
are eliminated.
Tested on an ASRock H81M-HDS and an Acer C720. No issues with SATA
were observed.
