[PATCH] arm: dts: qcom: Add #power-domain-cells property

[rnayak@codeaurora.org (Rajendra Nayak)]

clock controller nodes which also support power domains (gdscs') need
to have a #power-domain-cells property. Add these for gcc and mmcc
nodes of msm8974, gcc of apq8084 and msm8916.
Also update gcc and mmcc bindings for it.

Andy, the rest of the power domain (gdsc) support patches are
pulled in by Stephen into clk-next. Can you please pull the dts
changes in for 4.4.
