Add the function get_vf2pf_offset() to adf_pfvf_ops to differentiate the CSRs used for pf2vf and vf2pf. Offsets may or may not be direction specific depending on QAT generation. Since in QAT GEN2 the CSR is not direction specific, i.e. there is a single mailbox register shared for pf2vf and vf2pf, both get_vf2pf_offset() and get_vf2pf_offset() will return the same offset. This change is to make the direction explicit, so it is easier to understand and debug and also in preparation for the introduction of PFVF support in the qat_4xxx driver since QAT GEN4 devices have a separate CSR for pf2vf and vf2pf communications.

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.
