Any rules using engine matching are currently broken due RTP processing happening too in early init, before the list of hardware engines has been initialised.

Fix this by moving workaround processing to later in the driver probe sequence, to just before the processed list is used for the first time.

Looking at the debugfs gt0/workarounds on ADL-P we notice 14011060649 should be present while we see, before:

GT Workarounds 14011059788 14015795083

And with the patch:
