Light doesn't speed up or slow down when it passes through a
gravitational field. It may gain energy or lose energy or change
direction, but it doesn't change speed. You can arrange to emit two
photons in different directions from the same point and have them both
pass through another point at different times by having one pass through
a region of greater spacetime curvature, but that doesn't mean one
photon traveled faster than the other -- it means one traveled farther
than the other. Both traveled at the same speed, and all observers will
measure the same speed for both photons.
You need to read and understand a good book on relativity theory. I
suggest _Spacetime Physics_ by Taylor and Wheeler for an introduction.
If you are then able to understand _Gravitation_ by Misner, Thorne, and
Wheeler you will be doing better than I am.
