Robin Murphy b4ceb4a535 iommu: Tidy up Kconfig for SoC IOMMUs
Wacky COMPILE_TEST dependencies based on who used to define
dev_archdata.iommu can go.

Dependencies on ARM or ARM64 already implied by the ARCH_* platform
selection can go.

The entire IOMMU_SUPPORT menu already depends on MMU, so those can go.

IOMMU_DMA is for the architecture's DMA API implementation to choose,
and its interface to IOMMU drivers is properly stubbed out if disabled,
so dependencies on or selections of that can go (AMD_IOMMU is the
current exception since the x86 drivers have to provide their own entire
dma_map_ops implementation).

Since commit ed6ccf10f2 ("dma-mapping: properly stub out the DMA API
for !CONFIG_HAS_DMA"), drivers which simply use the dma-mapping API
should not need to depend on HAS_DMA, so those can go.

And a long-dead option for code removed from the MSM driver 4 years ago
can also go.

README

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.
