The low-power-mode drive was set to DIV_4 for some of PINCTRL groups, while these groups should use DIV_1. This patch fixes the wrong PINCTRL configurations and adds a full drive-setup for the changed configs, just for completeness since the added values match the default configuration. Now WiFi SDIO communication works properly using legacy signaling mode if SDIO BUS clocked at 50MHz, which is a maximum SDIO clock rate on Tegra20.

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.
