[PATCH v3 0/5] coresight: syscfg: Extend configfs for config load

[Mike Leach]

This set extends the configfs support to allow loading and unloading of
configurations as binary files via configfs.

Additional attributes - load and unload are provided to in the
configurations group to implement the load functionality.

Routines to generate binary configuration files are supplied in
./tools/coresight.

Example generator and reader applications are provided.

Tools may be cross compiled or built for use on host system.

Documentation is updated to describe feature usage.

Changes since v2:
1) Rebased & tested oo coresight/next - 5.18-rc2
2) Moved coresight config generator and reader programs from samples to
tools/coresight. Docs updated to match. (suggested by Mathieu)
3) userspace builds now use userspace headers from tools/...
4) Other minor fixes from Mathieu's review.

Changes since v1:
1) Rebased to coresight/next - 5.16-rc1 with previous coresight config
set applied.
2) Makefile.host fixed to default to all target.
