Latest datasheet makes it clear that not all ES revisions of the H3 and M3-W have the 4-tap HS400 mode quirk, currently the quirk is set unconditionally for these two SoCs. Prepare to handle the quirk based on SoC revision instead of compatibility value by using soc_device_match() and set the TMIO_MMC_HAVE_4TAP_HS400 flag explicitly. The reason for adding a new quirks struct instead of just a flag is that looking ahead it seems more quirks needs to be handled in a SoC revision basis.

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.
