mdss: use alternate lcd timings in mdp perf check

To improve consistency across multiple display hardware vendors, use the
alternate panel timings when determining if a pipe configuration is possible
with the max MDP clock for secure layers. This prevents consumers from
seeing inconsistent behavior with secure buffers on different display
hardware.
