237483aa5c coresight: stm: adding driver for CoreSight STM component
This driver adds support for the STM CoreSight IP block, allowing any
system compoment (HW or SW) to log and aggregate messages via a

The CoreSight STM exposes an application defined number of channels

and channels made available to userspace via configfs.
