[PATCH]: SiS warning fixes

[PATCH]: SiS warning fixes

[Alan]

Somehow the sis_info133 external definition ended up in libata.h and that
was included by both drivers. However libata.h contains libata-* specific
internals and clashing defines like DRV_NAME so this makes a mess. Move
the extern into the C file and remove the warnings
