ACPI / scan: Clear match_driver flag in acpi_bus_trim()
Drivers should not bind to struct acpi_device objects that
acpi_bus_trim() has been called for, so make that function
clear flags.match_driver for those objects.
If that is not done, an ACPI driver may theoretically try to operate
a device that is not physically present.
Fixes: 202317a573b2 (ACPI / scan: Add acpi_device objects for all device nodes in the namespace)
