[Intel-gfx] [PATCH 1/5] drm/i915: Multiply the refresh by 1000 in TV mode validatiion

[yakui.zhao at intel.com]

From: Zhao Yakui <yakui.zhao at intel.com>

Now the actual refresh rate is returned by the function of drm_mode_vrefresh.
So multiply the refresh rate by 1000 in TV mode validation.

At the same time the error is expanded from 10 to 1000.
