[roll] Roll fuchsia [aml-canvas] Migrate to Driver Framework v2.
This change removes the DFv1 interface from AmlCanvas,
and adds a separate class AmlCanvasDriver to interact
with the driver framework v2.
AmlCanvas only interacts with the hardware interface
(registers, memory pinning) and serves the FIDL canvas
Device protocol, and AmlCanvasDriver is responsible for
acquiring hardware resources (MMIO and BTI), creating
AmlCanvas instances and publishing the child node to the
node hierarchy.
Test: added aml-canvas-driver-test
Test: On VIM3 and core.nelson
(1) Manually verified (ffx driver list-devices -v)
that both amlogic-display and amlogic-video drivers
can bind to the device.
(2) "display-tool squares" works.
Note that "display-tool" uses linear images which
must be configured as canvas images.
(3) flatland_display_compositor_pixeltests works.
This test creates capture buffers which must be
configured as canvas images.
(2) and (3) verify that the amlogic-display driver works
after the migration.
(4) amlogic_decoder_integration_test
This verifies that the video driver works after the
migration.

This repository contains Fuchsia's Global Integration manifest files.
All changes should be made to the internal version of this repository. Our infrastructure automatically updates this version when the internal one changes.
Currently all changes must be made by a Google employee. Non-Google employees wishing to make a change can ask for assistance via the IRC channel #fuchsia on Freenode.
First install Jiri.
Next run:
$ jiri init $ jiri import minimal https://fuchsia.googlesource.com/integration $ jiri update
Third party projects should have their own subdirectory in ./third_party.
