i2c: piix4: Change the parameter list of piix4_transaction function

Currently, `piix4_transaction()` accepts only one parameter, which is the
`i2c_adapter` information. This approach works well as long as SB800 SMBus
port accesses are confined to the piix4 driver. However, with the
implementation of a separate ASF driver and the varying address spaces
across drivers, it is necessary to change the function parameter list of
`piix4_transaction()` to include the port address. This modification
allows other drivers that use piix4 to pass the specific port details they
need to operate on.
