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.

Prefix: "mfd: tps68470: ". Rationale: easier to look for specific commits, by,
for example, running `git log --grep tps68470`.

It's also reasonable to grep by path instead
