Add a new method to write the processor device identified by _HID
ACPI0007, that is preferred over the Processor OpCode since ACPI 6.0.
Fixes booting arm using ACPI only since the Processor OpCode isn't
found valid by the Linux kernel.

At present only acpigen_write_integer() is exported for use by other code.
But in some cases it is useful to call the specific function depending on
the size of the value.
Export these functions and add a test.

Power to some devices is controlled by GPIOs. Add a way to generate ACPI
code to enable and disable a GPIO so that this can be handled within an

More complex device properties can be provided to drivers via a
device-specific data (_DSD) object.
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.
Add an implementation of this.

Add a new file to handle generating ACPI code programatically. This is
used when information must be dynamically added to the tables, e.g. the
SSDT.
Initial support is just for writing simple values. Also add a 'base' value
so that the table can be freed. This likely doesn't happen in normal code,
but is nice to do in tests.
