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.

|
description: |
|
|
The STM32 Low-Power Timer (LPTIM) is a 16-bit timer that provides several
|
|
functions
|
|
- PWM output (with programmable prescaler, configurable polarity)
|
|
- Trigger source for STM32 ADC/DAC (LPTIM_OUT)
|
|
- Several counter modes:
|
|
- quadrature encoder to detect angular position and direction of rotary
|
|
elements, from IN1 and IN2 input signals.
|
|
- simple counter from IN1 input signal.
