drm/msm/mdp5: Fix compilation warnings 

Following compilation warnings were observed for these files:

This happens because in the first case we were initializing a two
dimensional array with {0} and in the second case we were initializing a
struct containing two arrays with {0}.

Fix them by adding another pair of {}.
