msm: mdss: Allow mdss driver to carry more lazy buffers 



SMMU Virtulization limit depends on the page table format
for a 32bit table we can have 4GB as a limit.

Increase the virtual map range for mdss driver so that
it can allow more lazy buffers to be mapped.

This will help in cases where apps which are queued
once to display and are parked in background.
