interconnect: qcom: sdm660: Correct NOC_QOS_PRIORITY shift and mask
The NOC_QOS_PRIORITY shift and mask do not match what vendor kernel
defines [1]. Correct them per vendor kernel. As the result of
NOC_QOS_PRIORITY_P0_SHIFT being 0, the definition can be dropped and
regmap_update_bits() call on P0 can be simplified a bit.
