This adds the canvas module on Meson8, Meson8b and Meson8m2. The canvas IP is used by the video decoder hardware as well as the VPU (video output) hardware.
Neither the VPU nor the video decoder driver support the 32-bit SoCs yet. However, we can still add the canvas module to have it available once these drivers gain support for the older SoCs.
I have tested this on my Meson8m2 board by hacking the VPU driver to not re-initialize the VPU (and to use the configuration set by u-boot). With that hack I could get some image out of the CVBS connector. No changes to the canvas driver were required.
Due to lack of hardware I could not test Meson8, but I'm following (as always) what the Amlogic 3.10 vendor kernel uses. Meson8b is also not tested because u-boot of my EC-100 doesn't have video output enabled (so I couldn't use the same hack I used on my Meson8m2 board).
This series meant to be applied on top of "Meson8b: add support for the RTC on EC-100 and Odroid-C1" from [0]
