Make IOMMU_DEFAULT_LAZY default for when AMD_IOMMU config is set, which matches current behaviour. For "fullflush" param, just call iommu_set_dma_strict(true) directly. Since we get a strict vs lazy mode print already in iommu_subsys_init(), and maintain a deprecation print when "fullflush" param is passed, drop the prints in amd_iommu_init_dma_ops(). Finally drop global flag amd_iommu_unmap_flush, as it has no longer has any purpose.

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.
