drm/i915: fix 64bit divide
ERROR: "__udivdi3" [drivers/gpu/drm/i915/i915.ko] undefined!
ERROR: "__divdi3" [drivers/gpu/drm/i915/i915.ko] undefined!
Store the frequency in kHz and drop 64bit divisions.
v2: Use div64_u64 (Matthew)
v3: store frequency in kHz to avoid 64bit divs (Chris/Ville)
Fixes: dab9178333 ("drm/i915: expose command stream timestamp frequency to userspace")
