I would add a `depends on ACPI` item on the Kconfig entry so that the
CONFI_ACPI macro can be removed from usb-ljca, because our use case with
LJCA currently needs the ACPI binding.

Before, I just tried to make it compatible with other platforms that
don't support ACPI but want to use LJCA device. But, We don't have
this use case until now.
