Introduce virtual host driver for ExynosAuto v9 UFS mHCI. The VH (Virtual Host) only supports data transfer functions so most of physical features must be disabled by setting the following quirks: - UFSHCD_QUIRK_BROKEN_UIC_CMD - UFSHCD_QUIRK_SKIP_PH_CONFIGURATION Before initialization, the VH must wait until PH is ready. This wait is currently implemented via polling.

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.
