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?

Dmitry, thanks for spotting this!  This is really an unintended leftover
from debugging.  I will drop it in v2.  For address alignment with
downstream, I do not really have a strong opinion and I can live with
either of them :)
