PS13, Line 30: struct soc_tcss_ops tcss_ops;

You could then add 
`register "common_soc_config.tcss_ops" = "{.valid_tbt_auth = intel_ht_supported}"`

or something similar, for example, which is nonsense.

I think the better place would be to create a new tcss.c file in tigerlake/ and alderlake/ directories; for now it can only contain

```
const struct soc_tcss_ops tcss_ops = {
        .configure_aux_bias_pads = tcss_configure_aux_bias_pads_regbar.
        .valid_tbt_auth = tcss_valid_tbt_auth,
};
```

and then the common/blocks/tcss.h can include

```
extern const struct soc_tcss_ops tcss_ops;
```

and then fsp_params.c probably doesn't need to pass the structures into the tcss_configure() function anymore; the `tcss_ops` struct could be used directly in common/block/tcss.c

WDYT?
