In this case, the vsram/vproc constraints for MT7622 and MT7623 were supposed to be the same as MT2701 (and a number of other SoCs), but that turned out to be a mistake because the aforementioned two SoCs' maximum voltage for both VPROC and VPROC_SRAM is 1.36V. Fix that by adding new platform data for MT7622/7623 declaring the right {proc,sram}_max_volt parameter.
