When I2C is disabled, we get a link error:
drivers/platform/built-in.o: In function `cht_int33fe_remove':
intel_cht_int33fe.c:(.text+0x8ba): undefined reference to `i2c_unregister_device'
drivers/platform/built-in.o: In function `cht_int33fe_probe':
intel_cht_int33fe.c:(.text+0x9ec): undefined reference to `i2c_acpi_new_device'
intel_cht_int33fe.c:(.text+0xa7a): undefined reference to `i2c_unregister_device'
This adds a Kconfig dependency to ensure I2C is available to this
driver.
