This driver only covered one scenario in which ACPI devices with _HID
INT3472 are found, and its functionality has been taken over by the
intel-skl-int3472 module, so remove it.

- If you say yes here you get support for the TPS68470 series of
- Power Management / LED chips.

- These include voltage regulators, LEDs and other features
- that are often used in portable devices.
-
- This option is a bool as it provides an ACPI operation
- region, which must be available before any of the devices
- using this are probed. This option also configures the
- designware-i2c driver to be built-in, for the same reason.
