bindings: Add device-tree bindings for qseecom driver

* QSEECOM (QTI Secure Execution Environment Communicator)

Required properties:

- compatible : Should be "qcom,qseecom"

- reg : should contain memory region address reserved for loading secure apps.

- qcom,disk-encrypt-pipe-pair : indicates what CE HW pipe pair is used for disk encryption

- qcom,file-encrypt-pipe-pair : indicates what CE HW pipe pair is used for file encryption

- qcom,support-multiple-ce-hw-instance : indicates if multicore CE support is supported.

- qcom,hlos-num-ce-hw-instances : indicates number of CE HW instances hlos can use.

- qcom,hlos-ce-hw-instance : indicates what CE HW is used by HLOS crypto driver

- qcom,qsee-ce-hw-instance : indicates what CE HW is used by secure domain (TZ) crypto driver

- qcom, msm_bus,name: Should be "qseecom-noc"

- qcom, msm_bus,num_cases: Depends on the use cases for bus scaling

- qcom, msm_bus,num_paths: The paths for source and destination ports

- qcom, msm_bus,vectors: Vectors for bus topology.

- qcom,ce-opp-freq: indicates the CE operating frequency in Hz, changes from target to target.

- qcom,full-disk-encrypt-info : Vectors defining full disk encryption unit, crypto engine, pipe pair configuration in <unit#, ce#, pipe-pair#>

- qcom,per-file-encrypt-info : Vectors defining per file encryption unit, crypto engine, pipe pair configuration in <unit#, ce#, pipe-pair#>

Optional properties:

  - qcom,support-bus-scaling : indicates if driver support scaling the bus for crypto operation.

  - qcom,support-fde : indicates if driver support key managing for full disk encryption feature.

  - qcom,support-pfe : indicates if driver support key managing for per file encryption feature.

  - qcom,no-clock-support : indicates clocks are not handled by qseecom (could be handled by RPM)

  - qcom,appsbl-qseecom-support : indicates if there is qseecom support in appsbootloader

  - vdd-hba-supply   : handle for fixed power regulator

  - qcom,qsee-reentrancy-support: indicates the qsee reentrancy phase supported by the target

  - qcom,commonlib64-loaded-by-uefi: indicates commonlib64 is loaded by uefi already

  - qcom,fde-key-size: indicates which FDE key size is used in device.

Example:

	qcom,qseecom@7f00000 {

		compatible = "qcom,qseecom";

		reg = <0x7f00000 0x500000>;

		reg-names = "secapp-region";

                qcom,disk-encrypt-pipe-pair = <2>;

                qcom,file-encrypt-pipe-pair = <0>;

		qcom,support-multiple-ce-hw-instance;

		qcom,hlos-num-ce-hw-instances = <2>;

		qcom,hlos-ce-hw-instance = <1 2>;

		qcom,qsee-ce-hw-instance = <0>;

		qcom,support-fde;

		qcom,support-pfe;

		qcom,msm_bus,name = "qseecom-noc";

		qcom,msm_bus,num_cases = <4>;

		qcom,msm_bus,active_only = <0>;

		qcom,msm_bus,num_paths = <1>;

		qcom,no-clock-support;

		qcom,appsbl-qseecom-support;

                qcom,fde-key-size;

		qcom,msm_bus,vectors =

			<55 512 0 0>,

			<55 512 3936000000 393600000>,

			<55 512 3936000000 393600000>,

			<55 512 3936000000 393600000>;

		qcom,ce-opp-freq = <100000000>;

		vdd-hba-supply = <&gdsc_ufs>;

	};

Example: The following dts setup is the same as the example above.

	qcom,qseecom@7f00000 {

		compatible = "qcom,qseecom";

		reg = <0x7f00000 0x500000>;

		reg-names = "secapp-region";

		qcom,support-fde;

		qcom,full-disk-encrypt-info = <0 1 2>, <0 2 2>;

		qcom,support-pfe;

		qcom,per-file-encrypt-info = <0 1 0>, <0 2 0>;

		qcom,qsee-ce-hw-instance = <0>;

		qcom,msm_bus,name = "qseecom-noc";

		qcom,msm_bus,num_cases = <4>;
