Derong Liu 43e5fee317 mmc: mtk-sd: Add wait dma stop done flow 
We found this issue on a 5G platform, during CMDQ error handling, if DMA
status is active when it call msdc_reset_hw(), it means mmc host hw reset
and DMA transfer will be parallel, mmc host may access sram region
unexpectedly. According to the programming guide of mtk-sd host, it needs
to wait for dma stop done after set dma stop.

This change should be applied to all SoCs.

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.
