drm/i915: Skip FDI vs. dotclock sanity check during readout

Browse Source 
The VBIOS/GOP may not program the FDI M/n vs. dotclock entirely
consistently. Eg. on a SNB Thinkpad X220 LVDS I see dotclock of
69.286 MHz (the best the DPLL can do) vs. FDI M/N 69.3 MHz
(matches what the EDID actually declares).
