hwmon: (pc87360) Introduce a #define for the driver name and use it

Make use of the cpp symbol DRIVER_NAME to set the driver's name and also
as name for devm_request_region(). While at it add a module alias using
the new define.

This is a preparation for the next cleanup commit that removes a cyclic
dependency between pc87360_driver (which references pc87360_probe in
.probe) and pc87360_probe() (which used pc87360_driver.driver.name).
