msm_fb: display: remove extra mdp4_dsi_cmd_clk_check()

Since mdp4_dsi_cmd_clk_check() is called inside of
mdp4_dsi_cmd_pipe_commit() also, mdp4_dsi_cmd_clk_check()
is called two times from pan display route. This patch
remove mdp4_dsi_cmd_clk_check() from mdp4_dsi_cmd_overlay()
to avoid mdp4_dsi_cmd_clk_check() called twice from
pan display route.

msm_fb: display: change TE simulation and read pointer interrupt timing

The current parameters for command mode TE simulation on mdp side are
not straightforward and cause double read pointer interrupts. Now make
read pointer interrupt and line counter reset happen right at h/w
vsync, and kick_off start position and height are set to back porch
and max respectively, so timing is much simplified and the chance of
tearing is reduced.

msm_fb: display: provision of mixer reset function

Mdp has hardware bug which cause fetch engine stalled if less than
3 pixels at begin or end of line be cropped into destination. Reset
mixer can fix this problem. However frame work can provide better
work around solution by falling back to gpu if the condition detected.
This patch will not reset mixer but provide mixer reset function in
case of mixer reset is need in future.

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: Program source address registers correctly

Scale filter FIR uses the adjacent pixels as part of the
processing. Source address registers should be program such that
they point to the first valid pixel so that non-ROI pixels are
ignored. This is done by making source x,y offsets to zero and
adding the computed offset to source address.
