Jesse Barnes d660467c3f drm/i915: prevent FIFO calculation overflows on 32 bits with high dotclocks 
A very high dotclock (e.g. 229500kHz as reported by Anton) can cause
the entries_required variable to overflow, potentially leading to a
FIFO watermark value that's too low to support the given mode.  Split
the division across the calculation to avoid this.
