drm/probe-helper: Introduce .force_ctx() connector callback

Browse source

The .force() connector callback is invoked by
drm_helper_probe_single_connector_modes() while the modeset acquire
context it created is live, but the hook signature provides no way to
pass it down, e.g. to support implementations needing to lock further
objects.

Add a .force_ctx() variant to drm_connector_helper_funcs, taking the
acquire context and returning an error code, so that -EDEADLK propagates
into the existing retry path.  When provided, it takes precedence over
drm_connector_funcs' .force(), which is kept for existing users.

This is a prerequisite for SCDC status synchronization in the HDMI
connector framework.
