This series adds ACPI-based PMT discovery support and wires it into the
Intel PMC telemetry stack for Nova Lake S.

Today, PMT discovery flow is primarily PCI-oriented. Some platforms expose
PMT discovery via ACPI _DSD, and PMC telemetry needs to consume that path
for both standalone and companion-device cases. This series addresses that
in three logical steps:

    1. Prepare intel_vsec for ACPI-backed discovery
    2. Refactor PMT class handling so discovery source is
       abstracted (PCI or ACPI)
    3. Add/enable PMC consumers using ACPI discovery, including NVL
       SSRAM support

Patches for step 1 were previously accepted. V2 includes the remaining
integration patches plus a new patch addressing review feedback on
cleanup.h patterns in ssram_telemetry.c.

Series layout

    01-06: intel_vsec cleanup/generalization for ACPI-capable discovery
           plumbing. Previously posted and accepted.

    07-12: PMT class refactor and ACPI discovery-source support
           Major patches:
           Patch 12 - adds ACPI support in PMT driver

    13-17: PMC driver integration
           Major patches:
           Patch 15 - adds ACPI discovery support in ssram driver
           Patch 17 - adds NVL IDs for SSRAM discovery

           Notable changes in V2:
           Patch 14 - new commit fixing __free() cleanup patterns per Ilpo's review
