hwmon/it87: Remove the SMBus interface support
This interface was useless as the LPC ISA-like interface is always
available, is faster, and is more reliable. This cuts the driver
size by some 20%.
This change is also required to later convert the it87 driver to a
platform driver, so that we can get rid of i2c-isa in a near future.

-When: January 2007

+Hardware Interfaces
+-------------------
+
+All the chips suported by this driver are LPC Super-I/O chips, accessed
+through the LPC bus (ISA-like I/O ports). The IT8712F additionally has an
+SMBus interface to the hardware monitoring functions. This driver no
+longer supports this interface though, as it is slower and less reliable
+than the ISA access, and was only available on a small number of
+motherboard models.
