hwmon: (sis5595) 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 use
it instead of all explicit usages of the same string. Also make use of
it instead of sis5595_driver.driver.name which breaks a cyclic dependency
between sis5595_probe() and sis5595_driver that in the next commit allows
to drop some forward declarations.
