disp: msm: sde: wait for lp2 and pm_suspend frame trigger

Browse Source 
PM_SUSPEND API adds extra pm_runtime refcount and calls
the device driver for pm_suspend. At this point display
device may not be in power collapse state. This patch
makes sure that crtc_commit thread is idle and triggers
power collapse also.
