soc: qcom: smd: Implement id_table driver matching
Implement a id_table based driver maching mechanism for drivers that binds to fixed channels and doesn't need any additional configuration, e.g. IPCRTR and DIAG. Signed-off-by: Bjorn Andersson <bjorn.andersson@sonymobile.com> Signed-off-by: Andy Gross <agross@codeaurora.org>
