overlay: Remove optimization that prevents garbage collection
There is an optimization to not do garbage collection (and thus UNSET)
if pipe usage hasn't change, added during older chip time frames.
It worked then because, continuous overlay failures were not normal,
and on failure userspace didn't UNSET remaining pipes.
On newer chips, owing to bandwidth limitations, continuous overlay
failures could happen, plus now we UNSET all other pipes. Thus each
round if GPU gets used, the optimization infers that pipe usage hasn't
changed and does not UNSET pipes.
Also the optimization doesn't do anything useful than saving a few
loops, but is suicidal in current situations, so can safely be done
away with.

hwc/overlay: Force pipe config if list geometry changes
Force pipes of a display, whose geometry has changed, to pass
configuration arguments using MSMFB_SET_IOCTL. This helps the driver
make additive bandwidth calculations and reject the frame if the
requirements go beyond what the hardware can support.
This change still preserves the optmization to avoid ioctl calls, in
cases where pipe params are the same but makes an exception when
list geometry changes.

overlay: Remove overloading external display with writeback
Remove the APIs that allow overloading external display with writeback
display. This was a hack until the framework used hwc to do writeback.

hwc/overlay: Prevent pipes from switching mixers
For split displays, earlier we allowed pipes to switch mixers in
subsequent rounds. This change prevents that and makes sure there
is one composition round where a pipe being transferred to another
mixer of the same display is UNSET

overlay: Fix crash due to small debug buffer size
The debug buffer size is insufficient for newer targets with multiple
pipes. The code causing crash is enabled only if the PIPE_DEBUG macro
is enabled during local debugging.
We now increase the buffer size and also put some string operations under
the macro check for efficiency.
