Coresight changes for v5.17

Hi Greg,

I'm sending this a little early due to the holiday schedule.  There might be
another pull request for rc8 in January - let's see when we get there. 
 
This pull request includes:

- A patch that uses devm_bitmap_zalloc() instead of the open-coded
equivalent.

- Work to make coresight complex configuration loadable via modules.

- Some coresight documentation updates.

Signed-off-by: Mathieu Poirier <mathieu.poirier at linaro.org>
