[PATCH v7 18/21] arm64: tegra: Add clock-cells property to Tegra PMC node

Sowjanya Komatineni

Tegra132 and Tegra210 PMC block has clk_out_1, clk_out_2, clk_out_3,
and a blink clock as a part of PMC.

These clocks are moved from clock driver to pmc driver with pmc as a
clock provider.

Clock ids for these clocks are defined in pmc dt-bindings.

This patch updated device tree to include pmc dt-binding and adds
#clock-cells property with one clock specifier to pmc node.
