msm: display: Fix composition issues when framework rebooted in suspend.

Currently, if framework is rebooted while in suspend mode, borderfill
is not unset due to which MDP composition can not be enabled. This patch
fixes the issue.

msm_fb: display: add one more pipe_commit delay before free ion buffer

It is possible that two consective pipe_commits happen within
same vsync period.  This will cause iommu page fault due to an ion buffer
that is being fetched by mdp's pipe is freed. It needs one pipe_commit
delay to free ion buffer to prevent iommu page from happening. Therefore
an extra free stage is needed to empty ion buffer free list.
Also, ION_IOMMU_UNMAP_DELAYED flag is not necessary at mapping of an
ion buffer since one pipe_commit delay had been added.

msm_fb: display: balance bus bandwidth on mdp axi port0 and port1

mdp read and write clients are connected on both mdp port0 and port1,
however, the bus bandwidth request is made on only port0. This change
divides mdp bw requests to port0 and port1 based on pipe connections
to mdp ports.
ab - no scaling factor - port0 and port1 split
ib - scaling factor - port 0 and port1 split

msm_fb: display: add scaling factor for mdp ab

system profiling found that mdp downscaling needs larger bandwidth
that is related to mdp ab request, so adding scaling factor to mdp ab
calculation reduces the chance of underruns.

ab - scaling factors - port0 and port1 split
ib - 1.5 x ab - no split and same on both ports

msm_fb: display: disable mdp blt mode

The switch of blt mode may cause mdp hang on some targets. To avoid
blt switch, we won't allocate the pipe that requires blt
mode. Basically this implies two things: downscaling is done by
rotator and gpu composition is used in case of blt mode is needed.

This implementation is to calculate mdp clk requirement based on the
req data passed from userspace before setting the actural pipe
data. If overlay_set asks for mdp clk that is greater than
mdp_max_clk, meaning blt is needed, overlay_set returns before pipe
allocation or pipe data change, so this way can avoid mdp to work on
wrong pipe data.

msm_fb: Fail fb2 open if called during suspend

At present, if msm_fb_open() for fb2 is called during suspend,
we increment the ref_count for fb2 and return success without
turning on the writeback pipeline. This causes the WFD client
think that fb2 is successfully opened whereas fb2_open should
not successful during suspend. Hence, return error if msm_fb_open()
is called for fb2 during suspend.
