Convert Qualcomm SCM firmware binding to the yaml format.

Signed-off-by: David Heidelberg <david@ixit.cz>

This patch comes with followup question -> since not all definitions
follow `"qcom,scm-*chipset*", "qcom,scm"`, should I change them or adjust this
binding to cover all cases?

I don't remember why some platforms has the generic "fallback" and
others doesn't. I don't have any objections to defining the binding as
you've done.

I don't think there's value in the formatting, so perhaps omitting the
pipe?

Can we include dt-bindings/clock/qcom,gcc-msm8916.h and continue to use
the constants in the example?
