Subject: [PATCH RFC 00/15] coresight: make drivers modular

Goal of this patchset is to make coresight drivers modular and enable
them by default in the arm64 and arm defconfigs. This is work-in-progress
and completely untested. Mainly, module exit calls are incomplete or
missing. Posting here to get early feedback.

Please review.

Thanks you,

Best regards,
Yousaf
