Mark switch cases where we are expecting to fall through.
This patch fixes the following warning (Building: arm):
drivers/dma/imx-dma.c: In function ‘imxdma_xfer_desc’:
drivers/dma/imx-dma.c:542:6: warning: this statement may fall through [-Wimplicit-fallthrough=]
if (slot == IMX_DMA_2D_SLOT_A) {
^
drivers/dma/imx-dma.c:559:2: note: here

Notice that, in this particular case, the code comment is
modified in accordance with what GCC is expecting to find.

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.
