drm/i915: Extract intel_crtc_dotclock() 



Extract intel_crtc_dotclock() from ddi_dotclock_get(). We'll reuse
this during state computation in order to determine the actual final
dotclcok after the DPLL computation has been done (which may not give
us the exact same port_clock that we fed in).

v2: Add the prototype
