Re-implement the decision making for soft state polling. Instead of generating the soft state mask in sfp_soft_start_poll() by looking at which GPIOs are available, record their availability in sfp_sm_mod_probe() in sfp->state_hw_mask. This will then allow us to clear bits in sfp->state_hw_mask in module specific quirks when the hardware signals should not be used, thereby allowing us to switch to using the software state polling.

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.
