f9189d5ada acpi: Add support for writing a Power Resource
These are used in ACPI to disable power to various pats of the system when
in sleep. Add a way to create a power resource, with the caller finishing

0667900049 acpi: Support copying properties from device tree to ACPI
Some drivers in Linux support both device tree and ACPI. U-Boot itself
uses Linux device-tree bindings for its own configuration but does not use
ACPI.

It is convenient to copy these values over to the ACPI DP table for
passing to linux. Add some convenience functions to help with this.

0e5a0a00d6 acpi: Support writing Device Properties objects via _DSD
More complex device properties can be provided to drivers via a

To create this we need to build it up in a separate data structure and
then generate the ACPI code, due to its recursive nature.
