That doesn't sound correct. If a config option is specified in DT or the
mapping table, it should be applied to HW. If someone doesn't want a
particular config option applied, then it simply shouldn't be mentioned
in DT or the mapping table.

IIUC, BIAS_DEFAULT should be used only on HW where there is a concept of
a true default bias, and in that case, that is what should be applied.
