    drm/i915/vlv: re-enable hotplug detect based probing on VLV/BYT


lspci:
--------------------
00:02.0 VGA compatible controller: Intel Corporation ValleyView Gen7 (rev 0a)


Description:
--------------------
Test with latest -next-queued kernel, there's "*ERROR* GT fifo" in dmesg when machine boot up. I tested other IVB platform, there's not this issue. Older kernels also reproduceable. We are testing Baytrail machine recently, and it might not be a regression. 

Error:
--------------------
[    2.710082] [drm:valleyview_enable_rps] *ERROR* GT fifo had a previous error 10

This is actually a BIOS bug.  I've filed a bug with them to investigate, but it occurs even without the gfx driver loaded, so I'm marking as "not our bug" and reducing the message to a debug one.
