UPI topology discovery relies on data from KTILP0 (offset 0x94) and KTIPCSTS (offset 0x120) as well as on SKX but on Icelake Server these registers reside under UBOX (Device ID 0x3450) bus. This patch enables /sys/devices/uncore_upi_*/die* attributes on Icelake Server.

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.
