Kaushlendra Kumar c01cc6fe06 platform/x86: intel_telemetry: Fix PSS event register mask
[ Upstream commit 39e9c376ac ]

The PSS telemetry info parsing incorrectly applies
TELEM_INFO_SRAMEVTS_MASK when extracting event register
count from firmware response. This reads bits 15-8 instead
of the correct bits 7-0, causing misdetection of hardware
capabilities.

The IOSS path correctly uses TELEM_INFO_NENABLES_MASK for
register count. Apply the same mask to PSS parsing for
consistency.

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.
