drm/msm/mdp5: Update SSPP_MAX value

'SSPP_MAX + 1' is the max number of hwpipes that can be present on a MDP5 platform. Recently, 2 new cursor hwpipes were added, which caused overflows in arrays that used SSPP_MAX to represent the number of elements. Update the SSPP_MAX value to incorporate the extra hwpipes.

- This should be a fix for 4.11.
