Since it is big endian, 0 will be read rather than 1. The DWC3 Linux driver simply ORs the value if "snps,tx_de_emphasis_quirk" is set, so the 2 properties have no effect. (The driver doesn't clear the field either which is another problem). "snps,gctl-reset-quirk" is not documented nor used in the driver, so drop it as well.
