Merge "firmware: qcom: Add TZ log driver snapshot" into msm-4.9

* TZLOG (Trust Zone Log)

The tz_log driver is a platform device driver that exposes a debugfs

interface for accessing and displaying diagnostic information

related to secure code (Trustzone/QSEE).

Required properties:

- compatible : Should be "qcom,tz-log"

- reg        : Offset and size of the register set for the device

Optional properties:

- qcom,hyplog-enabled   : (boolean) indicates if driver supports HYP logger service.

- hyplog-address-offset : Register offset to get the HYP log base address.

- hyplog-size-offset    : Register offset to get the HYP log size parameter.

Example:

	qcom,tz-log@fe805720 {

		compatible = "qcom,tz-log";

                reg = <0xfe805720 0x1000>;

		qcom,hyplog-enabled;

		hyplog-address-offset = 0x410;

		hyplog-size-offset = 0x414;

	};

          This option enables a driver with a debugfs interface for messages

          produced by the Secure code (Trust zone). These messages provide

          diagnostic information about TZ operation.
