drivers: thermal: Handle min state clear condition properly

Currently thermal framework passes min_state value as ULONG_MAX to
clear the vote. But the min_state callback API for few cooling device
drivers are checking whether requested state is within cooling device
max limit or not. If it is not within max limit, it returns error.
It leads to a case where framework clears the request, but cooling
device is still holding previous request.

If min_state request is greater than max_state, cap the min_state
request to max state and apply max state vote for cooling device.
