dt-bindings: tegra30-actmon: Document OPP and interconnect properties

../../reset/reset.txt for details.

- reset-names: Must include the following entries:

  - actmon

- operating-points-v2: See ../bindings/opp/opp.txt for details.

- interconnects: Should contain entries for memory clients sitting on

                 MC->EMC memory interconnect path.

- interconnect-names: Should include name of the interconnect path for each

                      interconnect entry. Consult TRM documentation for

                      information about available memory clients, see MEMORY

                      CONTROLLER section.

For each opp entry in 'operating-points-v2' table:

- opp-supported-hw: bitfield indicating SoC speedo ID mask

- opp-peak-kBps: peak bandwidth of the memory channel

Example:

	dfs_opp_table: opp-table {

		compatible = "operating-points-v2";

		opp@12750000 {

			opp-hz = /bits/ 64 <12750000>;

			opp-supported-hw = <0x000F>;

			opp-peak-kBps = <51000>;

		};

		...

	};

	actmon@6000c800 {

		compatible = "nvidia,tegra124-actmon";

		reg = <0x0 0x6000c800 0x0 0x400>;

		clock-names = "actmon", "emc";

		resets = <&tegra_car 119>;

		reset-names = "actmon";

		operating-points-v2 = <&dfs_opp_table>;

		interconnects = <&mc TEGRA124_MC_MPCORER &emc>;

		interconnect-names = "cpu";

	};
