1. This overrides fbUpdatingRect optimization for primary.
2. sourceCrop and displayframe are always full screen for primary.

Remove support for overriding a layer's z to set it up for foreground.
This is unused and can be achieved using pipes staged at required

Read the maximum width mixer can output from drivers
and consider this in identifying if dual pipes are required
to support a layer. So far above 2K dimensions we are using dual
pipes, but 8x39 mixer output can be upto 2560. So there is no
need of dual pipes as long as pipe data is less than this limit.
Compare layer/panel resolutions against this limit to deduce
if there is a need for dual pipes or split.

Currently for Mdss rotator we manipulate the layer buffer dimensions
to be equal to what rotator's destination dimensions would be, so that
these could be fed to MDP. Instead, this patch introduces APIs in
rotator so that hwc can directly query destination crop, width, height,
format from rotator.
This also simplifies the updateSource() and configRotator() helpers.

1. Use MDP rotator to rotate RGB layers which are rendered by software
2. Restrict total number of rotator sessions to 4 for all displays
3. Disable RGB layer rotation for all MDP versions < MDP5

Source Split layers always if the driver indicates so by setting
the src_split_always in the capabilities sysfs node.
This is applicable to layers whose width > mixer's width, since
MDP clk rate is dependent on max(mixer_width, layer_width).
This feature can be enabled if the panel height is more than a
certain empirically derived value. Splitting always in those
cases can help with a lower voltage.

Remove opaque types like size_t, uintptr_t, intptr_t to support
32bit and 64bit processes together.
When a 64bit process creates a handle and a 32bit process validates
the incoming ints against expected ints, opaque types lead to
different and mismatching values.
Always use unit64_t for base address for 32bit and 64bit SF.
Use unsigned int for offset and size, since ION uses that.

Enable source split for targets with single dsi. This has the

* Mdss driver supports DMA-Multiplexing on wb interface
for certain targets. Add overlay get function to query
this info during pipe allocation for wb.
* UI Scaling on external is not supported on certain
targets due to the lack of availability of pipes with
scalars. Add overlay get function to query this info
to disable action-safe calcs, DRC and others which
require downscaling.

Clear overlay and layer-rot map from the top level caller of
composition, rather than from the place of actual intermediate
failure. This makes sure, even in cases of GPU comp failure,
overlay and layer-rot maps are cleared and eventually pipes unset.

Add support for returning pipes based on capabilities.
getPipe() API takes in pipe specifications like format class,
scaling, display, mixer, fb and decides what pipe to return.
The nextPipe() API is now just a private helper.

If using source split to stage 2 pipes on the same mixer stage,
the left pipe needs to be a higher priority than the right.
Add API in overlay to compare pipe priorities and use this in
source split config to stage pipes accordingly.
Add support for 1 pipe config for FB if updating rect is within 2048
pixels.

For dual DSI panels, when enabled partial update AND framebuffer rect
optimization, it is not necessary to update both the halves of
the framebuffer every frame. This channge adds support to update
framebuffer based on the updating region generated.

Add support for SourceSplit. The mixers are abstracted from hwc.
There would be no translations to mixer understood destinations.
1) If a layer's crop and position are < 2048, only 1 pipe can be used
irrespective of position.
2) Else 2 pipes can be used with the layer equally split, without
regard to position.

Send the entire frame (array of overlays) to driver, so that it would
check pipes params and the whole frame wrt bandwidth and SMP.
Now, the overlay's commit API just prepares an overlay object but
makes no ioctl calls.
If the driver finds the frame, as a whole, to be not ok, the
validation fails and overlay/hwc return silently.
If a certain overlay object is mis-configured or pipes are
unavailable, the driver sets the number of objects it processed.
Overlay uses this to dump the incorrect config.

When a rotator or mdp configuration for a display fails, reset the
layer-to-rotator mappings for that display and reset the release
fences for the rotator objects used for that display.
Note: The rotator itself is offline and not tied to any mixer. It is
from the mappings that we deduce which rotator object was used for
layers of which display. Also we don't delete rotator objects held
for a specific display, since during stability runs, failures could
repeat each round and we end up allocating and deallocating memory
unnecessarily. The rotator objects will be deleted automatically
when not required anymore.

A display could be split if its dimensions exceed 2048 or in case
of primary if we make it so via device tree property.
