dt-bindings: riscv: cpus: Clarify mmu-type interpretation
The current description implies that only a single address translation
mode is available to the operating system. However, some implementations
support multiple address translation modes, and the operating system is
free to choose between them.

Per the RISC-V privileged specification, Sv48 implementations must also
implement Sv39, and likewise Sv57 implies support for Sv48. This means
it is possible to describe all supported address translation modes using
a single value, by naming the largest supported mode. This appears to
have been the intended usage of the property, so note it explicitly.

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.
