Add a new compatible and related bindigns for the fpga-based "ad3552r" AXI IP core, a variant of the generic AXI DAC IP. The AXI "ad3552r" IP is a very similar HDL (fpga) variant of the generic AXI "DAC" IP, intended to control ad3552r and similar chips, mainly to reach high speed transfer rates using a QSPI DDR (dobule-data-rate) interface. The ad3552r device is defined as a child of the AXI DAC, that in this case is acting as an SPI controller. Note, #io-backend is present because it is possible (in theory anyway) to use a separate controller for the control path than that used for the datapath.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
