Fixed ops were already identical, this adds support for non-fixed ops by sharing between trion and lucid. This also changes the names for trion ops to be consistent with the rest. Note LUCID_PCAL_DONE is renamed to TRION_PCAL_DONE because it is wrong for lucid, LUCID_PCAL_DONE should be BIT(27). Next patch will address this.
