drm/msm/dpu: set dirty_fb flag while in self refresh mode

Browse source

While in virtual terminal mode with PSR enabled, there will be
no atomic commits triggered without dirty_fb being set. This
will create a notion of no screen update. Allow atomic commit
when dirty_fb ioctl is issued, so that it can trigger a PSR exit
and shows update on the screen.
