drm/i915/guc: Add onion teardown to the GuC setup
Starting with intel_guc_loader, down to intel_guc_submission
and finally to intel_guc_log.
v2:
- Null execbuf client outside guc_client_free (Daniele)
- Assert if things try to get allocated twice (Daniele/Joonas)
- Null guc->log.buf_addr when destroyed (Daniele)
- Newline between returning success and error labels (Joonas)
- Remove some unnecessary comments (Joonas)
- Keep guc_log_create_extras naming convention (Joonas)
- Helper function guc_log_has_extras (Joonas)
- No need for separate relay_channel create/destroy. It's just another extra.
- No need to nullify guc->log.flush_wq when destroyed (Joonas)
- Hoist the check for has_extras out of guc_log_create_extras (Joonas)
- Try to do i915_guc_log_register/unregister calls (kind of) symmetric (Daniele)
- Make sure initel_guc_fini is not called before init is ever called (Daniele)
v3:
- Remove unnecessary parenthesis (Joonas)
- Check for logs enabled on debugfs registration
- Rebase on top of Tvrtko's "Fix request re-submission after reset"
v4:
- Rebased
- Comment around enabling/disabling interrupts inside GuC logging (Joonas)
