msm_fb: display: Add support for 4 layer MDP composition

Add 4 layers composition support to MDP by allowing borderfill
pipe to be used as base layer of mdp blending. This releases
RGB1 base pipe which can be used as a general purpose pipe.

msm_fb: display: change ion memory map for mdp mixer2 writeback

One way that mdp mixer2 gets writeback address is to get ion memory fd
from userspace, then mdp driver maps this fd in kernel. When mdp iommu
domain was not enabled, this maps to a physical address. Now after mdp
iommu domain is enabled, the map is changed to an iommu virtual addr.

video: msm_fb: Wait for dma to finish before terminating

If writeback takes too long to finish, after calling _stop()
writeback client might deallocate buffers during the DMA causing faults.
To prevent this situation, make _stop() a blocking call that waits
for the writeback to finish before returning.

video: msm: Load correct default values to QSEED at init

The previous QSEED Table 1 values are not suitable values (would end up
smoothing and sharpening content which can lead to artifacts).

The values loaded by this patch are the suggested default values for QSEED
since they do not smooth or sharpen most content (bi-cubic filter), but
will slightly smooth low frequency components of the image (i.e. helps
reduce artifacts that produce sharp edges on content that is supposed to
be a constant color; often introduced by some video encoding algorithms).
