Subject: [PATCH v1 13/17] arm64: tegra: Add clock-cells property to Tegra pmc

Tegra pmc has 3 clocks clk_out_1, clk_out_2, clk_out_3 with mux and gate
for each of these clocks as part of pmc and Tegra pmc is the clock provider
for these clocks.

These clock ids are part of pmc dt-bindings.

This patch includes pmc dt-bindings and adds #clock-cells propert
 with 1 clock specifier to Tegra pmc node.
