Add hw limitation checks for MDP composition once
we identify actual layers for MDP. This should be generic
way for all basic hw limitations of underlying MDP/MDSS.
Current limitations:
- a-family : MDP can not handle alpha scaling.
- 8226 & 8974 : Can not handle if multiple layers need
downscaling and blending

At 90/270 degree rotations, if there is vertical or horizontal flip in
layer transform, it is wrongly interpreted by display HAL due to wrong
check. So Copybit destination rectangle width & height are not swapped
which leads to unwanted out-of-range scaling.

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.

Add device version inline checks for hardware devices.
Also fixes the issue of 8084 being treated as 8974v2
owing to the expanded range.

For 8x26, if there is only one layer which needs scale for
secondary display, while no scale for primary display, DMA
pipe is occupied by primary. If layer changed and need to
fall back to GLES composition, virtual display lacks DMA
pipe and error is reported.
To avoid this case, use GPU composition for virtual display
scaling case on 8x26.

1. For Color layer, set zero transform value on COPYBIT_TRANSFORM
otherwise it causes MDP IOMMU page fault at 90/270 degree rotation.
2. Color layer is part of Copybit context list, so no need to call
msm_copybit() explicitly for it, that will be called during flush.

For portrait videos case on WFD, driver supports multiplexing
of DMA pipe in LINE and BLOCK mode.

portrait case of virtual display.

Initialize release and acquire fence fds of Copybit context to -1.
Otherwise fd 0 gets closed in first call to msm_copybit, which is
valid fd and it leads to bad state if fd 0 is being used as stdin.

Use the low and high bandwidth values exported from driver per target
Use the low bandwidth value when the system has at least 1 video
mode panel, else use the high bandwidth value.
Newer targets could have bandwidth exceeding what an uint32 could
hold, so change the bytes read to be in gigs.
Do not use the framebuffer handle to get size, since the handle may
be null.

This change provides APIs for this mechanism. In a case where
pipeid corresponding to the layer needs to be reserved, then pipe
session could be initiated for that pipe. This will ensure that
the pipe is not garbage collected, and is manually destroyed when
the session (or pipe requirement) has been ended. This change
also provides the api to locally allocate the dest for the given
reserved overlay pipeid.

Check for downscale support only for layers which needs to
be downscaled. Fixes issue where we bail out for all layers having
width more than MAX_LAYER_WIDTH even when they don't need scaling.

To minimize usage of decimation when 4K x 2K video is played
on primary, split the yuv layer into 2 halves and configure
each layer to individual VG pipes. With this approach,
decimation can be avoided in some 4K x 2K video use cases,
thereby improving performance.

The current binder implementation is inflexible when it comes to
adding new input/output parameters. It also needs a lot of
boilerplate code written when adding a simple enable/disable type
command.
Instead, let clients specify the parcels they want to pass and
unparcel them at the end points only.
Please note that it is assumed that all commands coming in
need the same permission checks. If this is no longer the case,
some commands need to be split out on the receiver end in
IQService.cpp.
This change also simplifies the code end clients need to write.
They should be able to include QServiceUtils and call a single
function to set the binder up and make the call.
