To provide the iommufd_sw_msi() to the iommu core that is under a different
Kconfig, move it and its related functions to driver.c. Then, stub it into
the iommu-priv header. The iommufd_sw_msi_install() continues to be used by
iommufd internal, so put it in the private header.
Note that iommufd_sw_msi() will be called in the iommu core, replacing the
sw_msi function pointer. Given that IOMMU_API is "bool" in Kconfig, change
IOMMUFD_DRIVER_CORE to "bool" as well.
Since this affects the module size, here is before-n-after size comparison:

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.
