dt-bindings: clock: qcom: Fix @codeaurora email in Q6SSTOP

The servers for the @codeaurora domain are long retired and any messages
addressed there will bounce. Govind Singh has left the company which
appears to leave the Q6SSTOP clock controller binding unmaintained.

Move maintenance of the binding to the Qualcomm Clock Drivers maintainer
as suggested by Bjorn Andersson.
