For platforms with old api_version, don't display the punit info to be
backward compatible.

TPMI (Topology Aware Register and PM Capsule Interface) creates a
flexible, extendable and software-PCIe-driver-enumerable MMIO interface
for PM features.

SST feature is exposed via the TPMI interface on newer Xeon platforms.

Kernel TPMI based SST driver provides a series of new IOCTLs for userspace
to use.

Introduce support for the platforms that do SST control via TPMI interface.

Compared with previous platforms, Newer Xeons also supports multi-punit in a
package/die, including cpu punit and non-cpu punit. These have already
been handled in the generic code.

As the platform specific callbacks are needed in all cases, including
