acpi: thermal: display forced passive trip points in proc
Users can force a passive trip point for a thermal zone that does not
have _PSV defined in ACPI by setting the passive attribute in sysfs.
It's useful to display such trip points in /proc/acpi/thermal_zone.
.../TZ1/cooling_mode:<setting not supported>
.../TZ1/polling_frequency:polling frequency: 10 seconds
.../TZ1/state:state: ok
.../TZ1/temperature:temperature: 53 C
.../TZ1/trip_points:critical (S5): 110 C
.../TZ1/trip_points:passive (forced): 95 C
And if not set (passive is 0):
.../TZ1/trip_points:passive (forced):<not set>
