The series updates SDM660 interconnect bindings, driver and device tree
to add 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.

Changes for v2:
- Fix dt_binding_check issues
- Drop 'reg' change from DTS patch
- Add Tested-by tag from Bjorn
