Use the two functions: fdma_alloc_phys() and fdma_dcb_init() for rx
buffer allocation and use the new buffers throughout.
In order to replace the old buffers with the new ones, we have to do the
following refactoring:
- use fdma_alloc_phys() and fdma_dcb_init()
- replace the variables: rx->dma, rx->dcb_entries and rx->last_entry
with the equivalents from the FDMA struct.
- replace uses of sparx5_db_hw and sparx5_rx_dcb_hw with fdma_db and
fdma_dcb.
- add sparx5_fdma_rx_dataptr_cb callback for obtaining the dataptr.
- Initialize FDMA struct values.

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.
