Revert "drm/i915/dp: Zero the DPCD data before connection probe"
This reverts commit 97cdd7101079adc3c626d159c62d43de949516c8. Clearing the dpcd data means that if the fetch fails, any previous data will be lost. On eDP, this is no fun as we only fetch dpcd at init time, so the memset will destroy that the next time through.
