[intel-i915][vim-display] Update to new i2c protocol

Test: Boot nuc/vim2 and make sure edid is read successfully
Change-Id: I543d29c5e7e1f8c76938eddc5a9388b1cfbd4688

[intel-i915] Read hardware state at initialization

Test: Boot to virtcon on NUC/eve, run display-test
Change-Id: Ie64e56eb46097db82bf3e9d6354b83024a8d89f1

[intel-i915] Clean up some config validation

Add full max pipe pixel rate and port link rate calculations, instead
of relying on hardcoded 'common' configuration limits. Also account for
plane scaling in these calculations and fix the max plane width check.

Test: Boot to virtcon on NUC/eve, run display-test

[intel-i915] Split i2c/dp_aux into separate objects

Test: Boot to virtcon on NUC/eve
Change-Id: If2d56129c7818fc5a7dd73ba18e5b92aef37d07c

[display] Remove ddk calls from on_displays_changed

This change replaces get_info with per-display argument structs to
on_displays_changed, and it moves the display mode validation to a
posted task. This allow simpler locking in the impl drivers, and it
enables the addition of output parameters into the argument structs.

This change also causes ownership messages to be sent before display
changed messages. Update various clients to not rely on a particular
order of messages.

Test: Boot to virtcon/hotplug on NUC/vim/eve. Run gfxtest, gfxlatency,
and display-test

Change-Id: Id561ed7587037353c1aeeab96511481d74026bdc

[intel-i915] Separate ddis from pipes/transcoders

This change creates a standalone Pipe class which manages hardware
pipes and transcoders, which leaves displays to only manage ddis. This
allows more dynamic configuration of the hardware.

Test: Virtcon and hotplugging on skl NUC/kbl NUC/eve/acer, virtcon
switching, boot menu, display-test, vkcube on skl NUC.

[display] Add support for color layers

Test: display-test
Change-Id: I270351824d264e5c905a74b43a2c09079059bd94

[display] Implement new vsync API

This change adds a new vsync event to the display controller API removes
the present signal event. It also changes the behavior of the cursor
position API to clamp the cursor to the display, to sidestep the issue
of how vsync interacts with a cursor that isn't on the display.

Test: display-test, vkcube, vkcube_image_pipe_swapchain
Change-Id: I6f332e3709eef2c6e1c932581024c2149b65a2a1

This is a revert of the revert 455cc09565a4f9018cd9921e9184d857bc5b7133
with an additional fix in DdkSuspend to fix crashing during mexec.

Test: display-test, boot with zedboot image including change

[intel-i915] Reverting: Add support for rotation

This reverts commit d6377109658b0e074dc853474febb2016be4cff3.

Reason for revert: This commit generates a zedboot that fails
to boot the system on pixelbook.

[intel-i915] Move work out of bind

Devmgr doesn't handle mexec while devices are still binding. Reduce the
chance of this race condition by moving initialization work onto an
auxiliary thread.

[intel-i915] Improve dpll allocation

Share dplls when possible. Also, given that the sparse documentation on
HDPORT makes it difficult to be confident in how the feature is
handled, just ignore it for now. Support can be needed when something
actually needs it and better documentation is available.

[intel-i915] Back unused gfxmem with a scratch buffer

There are times during driver initialization and when mexecing where
there is nothing good to put on the display. To handle those cases,
back all unused graphics memory with a black scratch buffer (which is
quicker and easier than turning the display off and back on).

storage installations.
