To support the need for host specific tuning for SD high-speed mode, let's add two new optional callbacks, ->prepare|execute_sd_hs_tuning() and let's call them when switching into the SD high-speed mode. Note that, during the tuning process it's also needed for host drivers to send commands to the SD card to verify that the tuning process succeeds. Therefore, let's also share the corresponding functions from the core to allow this.

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.
