disp: msm: sde: add trusted UI support for SDE

Extends atomic check to validate TUI transition request aginst
SDE and non-SDE client states. Triggers HW assignment after
making sure current frame is  completely flushed out of HW
pipeline. Initiate the acquire after TUI end after restoring
the software states.
