Skylake driver does the controller init operation twice: - first during probe (only to stop it just before scheduling probe_work) - and during said probe_work where the actual correct sequence is executed
To properly complete boot sequence when iDisp codec is present, bus initialization has to be called only after _i915_init() finishes. With additional _reset_list preceding _i915_init(), iDisp codec never gets the chance to enumerate on the link. Remove the superfluous initialization to address the issue.
