    acpi: Change device properties to work as a tree
    
    There is a second ACPI _DSD document from the UEFI Forum that details
    how _DSD style tables can be nested, creating a tree of similarly
    formatted tables.  This document is linked from acpi_device.h.
    
    In order to support this the device property interface needs to be
    more flexible and build up a tree of properties to write all entries
    at once instead of writing each entry as it is generated.
    
    In the end this is a more flexible solution that can support drivers
    that need child tables like the DA7219 codec, while only requiring
    minor changes to the existing drivers that use the device property
    interface.
    
    This was tested on reef (apollolake) and chell (skylake) boards to
    ensure that there was no change in the generated SSDT AML.
