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.
