Convert generic PWM controller bindings to DT schema format using
json-schema. The consumer bindings are provided by dt-schema.

Changes since v3:
1. Remove pwm-consumers.yaml as they do not give anything new except
description.
2. Leave pwm.txt with consumers description.
3. Add acks.
Changes since v2:
1. Change also pwm-sprd.txt
Changes since v1:
1. Indent example with four spaces (more readable),
2. Change pattern for pwm nodes,
3. Remove $ref from #cells.
