Relocates the tcd into the fsl_dma_chan structure. This adjustment reduces the need to reference back to fsl_edma_engine, paving the way for EDMA V3 support. Unified the edma_writel and edma_writew functions for accessing TCD (Transfer Control Descriptor) registers. A new macro is added that can automatically detect whether a 32-bit or 16-bit access should be used based on the structure field definition. This provide better support 64-bit TCD with future v5 version.

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.
