As an initial preparation before adding the fwnode-based DW XPCS device support let's split the xpcs_create() function code up to a set of the small sub-functions. Thus the xpcs_create() implementation will get to look simpler and turn to be more coherent. Further updates will just touch the new sub-functions a bit: add platform-specific device info, add the reference clock getting and enabling. The xpcs_create() method will now contain the next static methods calls: xpcs_create_data() - create the DW XPCS device descriptor, pre-initialize it' fields and increase the mdio device refcount-er; xpcs_init_id() - find XPCS ID instance and save it in the device descriptor; xpcs_init_iface() - find MAC/PCS interface descriptor and perform basic initialization specific to it: soft-reset, disable polling. The update doesn't imply any semantic change but merely makes the code looking simpler and more ready for adding new features support. Note the xpcs_destroy() has been moved to being defined below the xpcs_create_mdiodev() function as the driver now implies having the protagonist-then-antagonist functions definition order.

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.
