thermal: Use thermal zone device id in netlink messages
This patch changes the function thermal_generate_netlink_event to receive a thermal zone device instead of a originator id. This way, the messages will always be bound to a thermal zone.

netlink event. Netlink socket initialization is done during the _init_

of the framework. Drivers which intend to use the notification mechanism

just need to call thermal_generate_netlink_event() with two arguments viz
|

(originator, event). Typically the originator will be an integer assigned
|

to a thermal_zone_device when it registers itself with the framework. The

(originator, event). The originator is a pointer to struct thermal_zone_device
|
||||
from where the event has been originated. An integer which represents the
|

thermal zone device will be used in the message to identify the zone. The
|
||||
event will be one of:{THERMAL_AUX0, THERMAL_AUX1, THERMAL_CRITICAL,
|

THERMAL_DEV_FAULT}. Notification can be sent when the current temperature
|
||||
crosses any of the configured thresholds.
