platform/x86: intel_telemetry: Fix swapped arrays in PSS output
The LTR blocking statistics and wakeup event counters are incorrectly
cross-referenced during debugfs output rendering. The code populates
pss_ltr_blkd[] with LTR blocking data and pss_s0ix_wakeup[] with wakeup
data, but the display loops reference the wrong arrays.
This causes the "LTR Blocking Status" section to print wakeup events
and the "Wakes Status" section to print LTR blockers, misleading power
management analysis and S0ix residency debugging.
Fix by aligning array usage with the intended output section labels.
