Subject: [PATCH RFC 01/15] Revert "drivers/hwtracing: make coresight-* explicitly non-modular"
This reverts commit 941943cf519f7cacbbcecee5c4ef4b77b466bd5c.
Keep the descriptions in the driver headers. Also extend the same
changes to the drivers added after the reverted commit.
Prepare to make Coresight infrastructure modular.
