Subject: [PATCH v2 1/4] dt-bindings: clock: fix wrong clock documentation for qcom,rpmcc

qcom,rpmcc describe 2 different kind of device.
Currently we have definition for rpm-smd based device but we lack
Documentation for simple rpm based device.

Add the missing clk for ipq806x, apq8060, msm8660 and apq8064 and
provide additional example to describe these new simple rpm based
devices.
