mainlining shenanigans

Double Transfer Rate (DTR) mode transfers data twice per clock cycle. Add support for parsing DTR ops and set up the registers to allow it. Most SPI NOR flashes expect 2 byte commands. Parse the 2-byte opcode from SPI MEM and set it up in the CQSPI_REG_OP_EXT_LOWER register. Increment the delay needed before issuing indirect writes because larger delay is needed for DTR mode. With the current delay some writes end up missing.

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.
