[PATCH] drm/i915: Skip all the
> gfx clock force on CHV

Please test this patch.

Patch this patch on latest nightly branch
commit:dbd79c545cbbf63785cbda8d13260b3e827f0f6d

S3 will not cause dmesg warn anymore, but seems S3 failed itself, when type
"echo mem > /sys/power/state", it will resume immediately.
