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.

|
The Amlogic Meson SoC UART Serial Interface is present on a large range
|
|
of SoCs, and can be present either in the "Always-On" power domain or the
|
|
"Everything-Else" power domain.
|
|
|
|
The particularity of the "Always-On" Serial Interface is that the hardware
|
|
is active since power-on and does not need any clock gating and is usable
|
|
as very early serial console.
