This reverts commit 3316ab2b45f6bf4797d8d65b22fda3cc13318890. The MHI spec owner pointed out that the SOC_HW_VERSION register is part of the BHIe segment, and only valid on devices which implement BHIe. Only a small subset of MHI devices implement BHIe so blindly accessing the register for all devices is not correct. Also, since the BHIe segment offset is not used when accessing the register, any implementation which moves the BHIe segment will result in accessing some other register. We've seen that accessing this register on AIC100 which does not support BHIe can result in initialization failures. We could try to put checks into the code to address these issues, but in the roughly 4 years this functionality has existed, no one has used it. Easier to drop this dead code and address the issues if anyone comes up with a real world use for it.

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.
