fix an issue of Fan device type sending command

[pInksenberg]

Issue Description: We onboarding Yeelight Fan(bridged device) device to ST App, but we are unable to control device by sending fan mode or speed.

Problem Analysis: Upon reviewing the logs, it was found that the command send to a wrong endpoint (endpoint 0 for the yeelight bridge instead of endpoint 68 for the yeelight fan). It was caused by the local function "component_to_endpoint" in matter-thermostat/init.lua 158. We revised the edge driver by adding an "elseif" statement for returning Fan device type related endpoint. (As per Matter Device Library Spec, there are 3 device type in HVAC, including Thermostat, Fan and Air Purifier. However, It should be noted that the Fan device is currently absent from the function "component_to_endpoint".)
