msm: display: dsi command mode vsync time generation

In each vsync cycle there will be two vsync interrupts
generated, need ignore the wrong one to provide the correct vsync
timestamp.

msm: mdp: Use a waitqueue for vsync notifications

Use a waitqueue instead of completions and make sure the vsync
show event always returns the timestamp except when it is
interrupted. This simplifies the vsync wait mechanism both here
and in userspace and avoids any unnecessary locking.

msm: mdp: Wait unconditionally in internal vsync waits

Do not wait for timestamp to change for internal waits as the
waitqueue can be woken up from places where the vsync timestamp
doesn't change.

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.

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.
