ddr_signaling is set to true for DDR50 and DDR52 modes but is not set back to false for other modes. This programs incorrect host clock when mode change happens from DDR52/DDR50 to other SDR or HS modes like incase of mmc_retune where it switches from HS400 to HS DDR and then from HS DDR to HS mode and then to HS200. This patch fixes the ddr_signaling to set properly for non DDR modes.

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.
