Current all acpi_bus_trim callers have rmdevice to 1.
that means it will remove all acpi devices.
When 0, is passed, it will keep the parent.
For root bus hotremove support, we need to have pci device to be
removed before acpi devices.
So try to keep all acpi devices, and only stop drivers with them.
This change should be safe because all current callers all have 1 passed.
