Check the DT structure, 8155-adp (so, de facto 8155) included 8150 before, but that was not exactly the correct approach.. It bit us after we accidentally discovered 8155 advertises MMCX, LCX and LMX PDs in cmd-db but triggers a bite on access attempts.. By mimicking the indices to match the ones of 8150, we only have to fix up the domains that were axed from 8155 (in comparison to 8150 which has the full fat setup).

Therefore it would be great if commit msg explained this. BTW, using here directly numbers matching SM8150 values, would also be backwards compatible...
