ata: ahci_st: Fix compilation warning
If CONFIG_OF is disabled and the ahci_st driver is builtin (or
CONFIG_MODULES is disabled), then using the macro of_match_ptr()
results in the st_ahci_match variable being unused, which generates a
compilation warning and a compilation error if CONFIG_WERROR is enabled.
Fix this by directly assigning st_ahci_match to .of_match_table in the
st_ahci_driver platform driver definition.
