drivers: qcom: rpmh: allow requests to be sent asynchronously
Platform drivers that want to send a request but do not want to block
until the RPMH request completes have now a new API -
rpmh_write_async().
The API allocates memory and send the requests and returns the control
back to the platform driver. The tx_done callback from the controller is
handled in the context of the controller's thread and frees the
allocated memory. This API allows RPMH requests from atomic contexts as
well.
