msm_fb: display: fix the suspend/resume hang caused by wait4vsync stuck

wait_for_completion in wait4vsync stucks after multiple suspend/resume
tests. The cause is that when show_event timeout happens, or vsync isr
is disabled for long time, wait_vsync_cnt resets to zero, and in vsync
isr complete_all has no chance to be called which caused mdp hang. So
complete_all needs to be called whenever show_event has timeouts.

msm_fb: display: Send pixel data while sending on/off commands

To avoid LCD off sequence violeation for some LCD vendors,
we need to keep sending video data during off/sleep commands.
This fixes issues seen while going to a suspend.

msm_fb: display: add mutex to video_off

It is possible  that pipe_commit still be issued by
frame work after suspend had been started. Therefore
mutex lock within video_off is necessary to prevent
race condition from happening between these two threads.

msm: display: vsync usage in turning off dsi video

Add timeout to waiting for vsync so that it can come out
when vsync interrupt is not working.
Need not wait for vsync after timing engine is off.

msm_fb: display: fix iommu page fault when iommu buffer freed

There has possibility that pipe commit come very close to next vsync.
This may cause two consecutive pipe_commits happen within same vsync
period which cause iommu page fault when previous iommu buffer is
freed since mdp stil fetching it. Set ION_IOMMU_UNMAP_DELAYED flag
at ion_map_iommu() to add delay un mapping iommu buffer to fix this problem.
Otherwise four buffer mechanism is needed to avoid this problem..
Also ion_unmap_iommu() may take long time to free an ion buffer. Move
mdp4_overlay_iommu_unmap_freelist(mixer) called after stage_commit()
to increase chance to have pipe_commit (up to stage_commit) is completed
within same vsync period
This patch also fix an potential race condition at wait_for_completion
between show_event thread and wait4vsync thread.

msm_fb: display: issue completion when disabling vsync irq

When vsync irq is disabled, vsync_wait_cnt is reset to zero and
completion is issued out as they are done in isr to make sure all
wait_for_completion is released.

mms_fb: display: init pipe default configure as solidfill

Initialize mdp pipes default config as solid fill so that
there will have no memory fetch if pipe are staged into
mixer while flush bits are left behind and set at next vsync.
This is will prevent mdp iommu page fault from happening
at address 0x00000000 during resume.

msm_fb: display: Do clock control within mdp4_hw_init

Since mdp4_hw_init() access mdp registers, mdp clock control
within mdp4_hw_init() is necessary.
