Matthias Schiffer 1aeda09666 spi: cadence-quadspi: allow operations with cmd/addr buswidth >1
With the removal of the incorrect logic of cqspi_set_protocol(), ops with
cmd/addr buswidth >1 are now working correctly.

Tested on a TI AM64x with a Macronix MX25U51245G QSPI flash using 1-4-4
operations.

DTR operations are currently untested, so we leave them disabled for now
(except for the previously allowed 8-8-8 ops).

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.
