soc: qcom: smd: Make callback pass channel reference
By passing the smd channel reference to the callback, rather than the smd device, we can open additional smd channels from sub-devices of smd devices. Also updates the two smd clients today found in mainline. Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org> Signed-off-by: Andy Gross <andy.gross@linaro.org>
