Create a spi_controller_mem_caps structure and put it within the spi_controller structure close to the spi_controller_mem_ops strucure. So far the only field in this structure is the support for dtr operations, but soon we will add another parameter. Also create a helper to parse the capabilities and check if the requested capability has been set or not.

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.
