stm class: Introduce an abstraction for System Trace Module devices A System Trace Module (STM) is a device exporting data in System Trace Protocol (STP) format as defined by MIPI STP standards. Examples of such devices are Intel(R) Trace Hub and Coresight STM. This abstraction provides a unified interface for software trace sources to send their data over an STM device to a debug host. In order to do that, such a trace source needs to be assigned a pair of master/channel identifiers that all the data from this source will be tagged with. The STP decoder on the debug host side will use these master/channel tags to distinguish different trace streams from one another inside one STP stream. This abstraction provides a configfs-based policy management mechanism for dynamic allocation of these master/channel pairs based on trace source-supplied string identifier. It has the flexibility of being defined at runtime and at the same time (provided that the policy definition is aligned with the decoding end) consistency. For userspace trace sources, this abstraction provides write()-based and mmap()-based (if the underlying stm device allows this) output mechanism. For kernel-side trace sources, we provide "stm_source" device class that can be connected to an stm device at run time.

stm class: dummy_stm: Add dummy driver for testing stm class This is a simple module that pretends to be an stm device and discards all the data that comes in.

stm class: Add heartbeat stm source device Heartbeat stm source may have multiple instances (for connecting to different stm devices). Each instance will send a periodic test message over its stm device when it is linked. This can be used for testing stm class framework, stm device drivers or as a heartbeat over the stm link.
