Subject[PATCH] drm/i915: set i915 driver probe to asynchronous
Date
From: Zhang Ning <ning.a.zhang@intel.com>

when i915 is built in module, and system has built-in display, eg. eDP,
i915 will detect and active it during driver probe. it will take long
time.

set i915 driver probe to asynchrous can save kernel initial time.
