turbostat: fix PC6 displaying on some systems
'MSR_PKG_CST_CONFIG_CONTROL' encodes the deepest allowed package C-state limit, and turbostat decodes it. Before this patch: turbostat does not recognize value "3" on Ice Lake Xeon (ICX) and Sapphire Rapids Xeon (SPR), treats it as "unknown", and does not display any package C-states in the results table. After this patch: turbostat recognizes value 3 on ICX and SPR, treats it as "PC6", and correctly displays package C-states in the results table.

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.
