Add compatible string and new attributes to support the Xilinx CAN FD core. Unlike the previously documented Xilinx CAN cores, the CAN FD core has TX mailboxes instead of TX FIFO, and optionally RX mailboxes instead of RX FIFO (selected at core generation time, not switchable at runtime). Add "tx-mailbox-count" and "rx-mailbox-count" to specify the mailbox counts instead of reusing "tx-fifo-depth" and "rx-fifo-depth". The RX FIFO depth is constant 32, but allow it to be specified via "rx-fifo-depth" to match DT usage with Zynq CAN (which has constant RX FIFO of depth of 64). v2: Remove unnecessary "rx-mode" DT property.

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 Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
