commitba9f39a785upstream. In commit5320226a05("mmc: core: Disable HPI for certain Hynix eMMC cards"), then intent was to prevent HPI from being used for some eMMC cards, which didn't properly support it. However, that went too far, as even BKOPS and CACHE ctrl became prevented. Let's restore those parts and allow BKOPS and CACHE ctrl even if HPI isn't supported.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
