All implementations of the .pin_to_portcr() method implement the same conversion from Port Control Register offset to virtual address. Factor it out into the two callers. Remove the pfc parameter, as it is no longer used. Note that the failure handling in r8a7740_pin_to_portcr() is pro forma, as the function is never called with an invalid pin number.

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.
