hwmon: (lm85) Use dynamic sysfs callbacks

This lets us get rid of macro-generated functions and shrinks the
driver size by about 10%. I used a new style suggested by Mark M.
Hoffman to retrieve the channel number. Instead of:

	struct sensor_device_attribute *sda = to_sensor_dev_attr(attr);
	int nr = sda->index;

I do:

	int nr = to_sensor_dev_attr(attr)->index;

This looks better, and even allows the compiler to do some minor
optimizations.
