[PATCH] I2C: Separate non-i2c hwmon drivers from i2c-core (3/9)
Convert the 10 ISA hardware monitoring drivers (it87, lm78, pc87360, sis5595, smsc47b397, smsc47m1, via686a, w83627hf, w83627ehf, w83781d) to explicitely register with i2c-isa. For hybrid drivers (it87, lm78, w83781d), we now have two separate instances of i2c_driver, one for the I2C interface of the chip, and one for ISA interface. In the long run, the one for ISA will be replaced with a different driver type. At this point, all drivers are working again, except for missing dependencies in Kconfig.
