Fix various inconsistencies in schema indentation. Most of these are list indentation which should be 2 spaces more than the start of the enclosing keyword. This doesn't matter functionally, but affects running scripts which do transforms on the schema files.

|
A canvas is a collection of metadata that describes a pixel buffer.
|
|
Those metadata include: width, height, phyaddr, wrapping and block mode.
|
|
Starting with GXBB the endianness can also be described.
|
|
|
|
Many IPs within Amlogic SoCs rely on canvas indexes to read/write pixel data
|
|
rather than use the phy addresses directly. For instance, this is the case for
|
|
the video decoders and the display.
|
|
|
|
Amlogic SoCs have 256 canvas.
