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

Bootstrapping gcc is the recommended way if your host gcc's version
doesn't match the gcc version you're going to build. While a build
with an outdated host gcc usually succeeds, an outdated gnat seems
to be a bigger issue.
v3: Some library controversy: gcc likes the libraries it ships with
most but we don't want to install shared libraries. So we build
them static --disable-shared) and install only the minimum
(libgcc, libada, libstdc++). However, as the code of these
libraries might be used to build a shared library we have to
compile them with `-fPIC`.
v4: o Updated getopt strings.
o The workaround for clang (-fbracket-depth=1024) isn't needed
for bootstrapping and also breaks the build, as clang is only
used for the first stage in that case and gcc doesn't know
that option.
So far build tested with `make BUILDGCC_OPTIONS="-b -l c,ada"` on
o Ubuntu 14.04 "Trusty Tahr" (i386)
o Debian 8 "Jessie" (x86_64) (building python (-S) works too)
o current Arch Linux (x86_64)
o FreeBSD 10.3 (x86_64) (with gcc-aux package)

Add the Audio DSP device for apollolake as a PCI driver with a static
scan_bus handler so generic devices can be declared under it.
This is for devices like the Maxim 98357A which is connected on the
I2S bus for data but has no control channel bus and instead just has
a GPIO for channel selection and power down control and needs to
describe that GPIO connection to the OS via ACPI.
