the systems which have minor fan configuration differences. This
reduces the amount of code used to describe such systems.
The capability registers provides system specific information about the
number of physically connected tachometers and system specific fan
speed scale parameter.
For example one system can be equipped with twelve fan tachometers,
while the other with for example, eight or six. Or one system should
use default fan speed divider value, while the other has a scale
parameter defined in hardware, which should be used for divider
setting.
Reading this information from the capability registers allows to use the

dt-bindings: cpu: Fix JSON schema

Commit fd73403a4862 ("dt-bindings: arm: Add SMP enable-method for
Milbeaut") added support for a new cpu enable-method, but did so using
tabulations to ident. This is however invalid in the syntax, and resulted
in a failure when trying to use that schemas for validation.

Use spaces instead of tabs to indent to fix this.
