The USDHC instances need the USDHC NAND and IPG clock in order to operate. Reference them properly by replacing the dummy clocks with the actual clocks. Note that both clocks are currently implicitly enabled since they are part of the i.MX 7 clock drivers init_on list. This might change in the future.
