The rest of the on-chip CMT devices support 48-bit counters and have 8 channels each. Based on the data sheet information "CMT2/3 are exactly same as CMT1" it seems that CMT2 and CMT3 now use the CMT1 compat string in the DTSI. Clarify this in the DT binding documentation by describing R-Car Gen3 and RZ/G2 CMT1 as "48-bit CMT devices".
