ata: libata-core: Allow forcing most horkage flags

To facilitate debugging of drive issues in the field without kernel
changes (e.g. temporary test patches), add an entry for most horkage
flags in the force_tbl array to allow controlling these horkage
settings with the libata.force kernel boot parameter.
