It adds the missing a2noc clocks required for QoS registers programming per downstream kernel[1].

Shawn, as you are at it, do we want to keep these nocs shifted compared to the downstream dtsi (so that the offset of QoS registers is 0) or we'd better introduce QoS register offset and move noc start address to the same address as in downstream?
