ACPI: register ACPI thermal zone as generic thermal zone devices
Register ACPI thermal zone as thermal zone device.
the new sys I/F for ACPI thermal zone will be like this:
/sys/class/thermal:
|thermal_zone1:
|-----type: "ACPI thermal zone". RO
|-----temp: the current temperature. RO
|-----mode: the current working mode. RW.
the default value is "kernel" which means thermal
management is done by ACPI thermal driver.
"echo user > mode" prevents all the ACPI thermal driver
actions upon any trip points.
|-----trip_point_0_temp: the threshold of trip point 0. RO.
|-----trip_point_0_type: "critical". RO.
the type of trip point 0
This may be one of critical/hot/passive/active[x]
for an ACPI thermal zone.
...
|-----trip_point_3_temp:
|-----trip_point_3_type: "active[1]"
