sconfig: Allow setting device status in device tree

For devices supporting both Linux and Windows, we may find some ACPI
devices that only need drivers in Linux and should not even be shown in
Windows Device Manager UI.

The new 'hidden' keyword in device tree 'device' statement allows
devices sharing same driver to call acpi_gen_writeSTA with different
values.
