msm: mdss: move rotator SMP reservation to rotator setup

Shared memory pool (SMP) blocks are limited, in some cases where there
are many overlay pipes used, we may not be able to get enough blocks for
rotator sessions. In such cases fall-back solution must be considered,
however for this to happen this would need to be identified during
rotator session setup. Move logic to do pipe resource reservation in
rotator setup if possible.
