pwm: Make info in traces about affected pwm more useful

2024-09-05T09:14:14Z

The hashed pointer isn't useful to identify the pwm device. Instead store and emit chipid and hwpwm. Signed-off-by: Uwe Kleine-König Link: https://lore.kernel.org/r/20240705211452.1157967-2-u.kleine-koenig@baylibre.com Signed-off-by: Uwe Kleine-König
