mb/google/nissa/var/uldren: Add ACPI DmaProperty for WLAN device

Add ACPI DmaProperty for WLAN device. `is_untrusted` is eventually
ended up by adding DMA property _DSD which is similar to what
`add_acpi_dma_property` does for WWAN drivers, hence it makes sense to
have a unified name across different device drivers.
