[PATCH] firmware: qcom: scm: Add sdm660 soc compatible

[Craig Tatlor]

Add the compatible for SDM660.
This does not need clocks to do scm calls

Do you need to update the driver? It looks like the scm driver should be
changed to just try and get all the clks it can and treat them as
optional clks, i.e. don't fail if they aren't actually listed in DT.
Then we can just have one qcom,scm compatible string in this driver but
we're free to add different compatibles to the binding for all the
different SoCs out there.

Andy picked my clock-rework patch for the scm driver, so we can now do:

	compatible = "qcom,scm-sdm660", "qcom,scm";

and get the desired result.


Please respin your patch without the code update.

Bjorn
