hwmon/it87: Remove the SMBus interface support

Browse source 
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.

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.
