Shawn Guo 13404ac888 interconnect: qcom: sdm660: Add missing a2noc qos clocks 
It adds the missing a2noc clocks required for QoS registers programming
per downstream kernel[1].  Otherwise, qcom_icc_noc_set_qos_priority()
call on mas_ufs or mas_usb_hs node will simply result in a hardware hang
on SDM660 SoC.
