ata: sata_gemini: Remove dependency on OF for compile tests

If CONFIG_OF is disabled, then using the macro of_match_ptr() results
in the gemini_sata_of_match variable being unused, which generates a
compilation warning and a compilation error if CONFIG_WERROR is enabled.

Removing the use of this macro by directly assigning the
gemini_sata_of_match match table to the .of_match_table field in the
platform driver definition allows removing the dependency on OF for
compile tests, thus improving compile test coverage.
