When using io_pgtable the correct pgsize_bitmap is stored in the cfg, both
v1_alloc_pgtable() and v2_alloc_pgtable() set it correctly.
This fixes a bug where the v2 pgtable had the wrong pgsize as
protection_domain_init_v2() would set it and then do_iommu_domain_alloc()
immediately resets it.
Remove the confusing ops.pgsize_bitmap since that is not used if the
driver sets domain.pgsize_bitmap.
Fixes: 134288158a ("iommu/amd: Add domain_alloc_user based domain allocation")

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.
