Instead of configuring the I2C mdiobus when SFP driver is probed, create/destroy the mdiobus before the PHY is probed for/after it is released. This way we can tell the mdio-i2c code which protocol to use for each SFP transceiver. Move the code that determines MDIO I2C protocol from sfp_sm_probe_for_phy() to sfp_sm_mod_probe(), where most of the SFP ID parsing is done. Don't allocate I2C bus if no PHY is expected.

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.
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.
