For the QOS registers, instead of using the raw values for calculation for each reg field, use a defined macro which takes in argument for all the reg fields to get the desired value. Do the similar simplification for QOS register and group registers and make the corresponding changes for am62a_qos_uboot file.

Looks a bit better IMHO,
