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.
