ACPI: add acpi_bus_get_status_handle()
Add acpi_bus_get_status_handle() so we can get the status of a namespace
object before building a struct acpi_device.
This removes a use of "device->flags.dynamic_status", a cached indicator of
whether _STA exists. It seems simpler and more reliable to just evaluate
_STA and catch AE_NOT_FOUND errors.
