regulator: Convert TPS62360 binding to json-schema

Convert the TPS62360 regulator binding to DT schema format
using json-schema.

This also removes redundant "ti,enable-force-pwm" property
from the example. The property description was removed from the
original text binding file by commit 9a00630c ("regulator:
tps62360: support force PWM mode via regulator mode"), but a
reference to it remained in the example.
