mb/google/fizz: Drop broken USB ACPI code
Fizz's USB ACPI code is intended to allow the OS to control port charging power, but since Fizz's ports are dumb (vs smart), it controls power to the port itself. The end result is that active ports become disabled when rebooting from Windows (10/11), and power is not restored until the device is powered down (a warm reboot is not sufficient). Subsequent Chromebox models (eg, Puff-based variants) don't bother with EC-controlled USB port power, so just drop it since it's problematic and provides no benefit. Test: boot Windows 10/11, reboot, observe active USB ports still functional (eg, USB KB still works) Change-Id: I2c13d49b3ce8de8b0a38512db3c57d0c8ecbf0ad Signed-off-by: Matt DeVillier <matt.devillier@gmail.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/58185 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Angel Pons <th3fanbus@gmail.com> Reviewed-by: Michael Niewöhner <foss@mniewoehner.de>
