When SST-TF is disabled, the TRL (Turbo Ratio Limit) of config level 0
is getting restored. But the TRL of current level should be restored
which may not be config level 0.
This is caused by a bug in treating config level as TRL level. So
arguments needs to be swapped.

SST BF and TF can be enabled/disabled per level. So check the current
level support from the mask of supported levels.
This change from a single level to mask for info.sst_tf_support and
info.sst_tf_support is indicated by API version change. Use as mask for
API version above 2. In this way there is no change in behavior when
running on older kernel with API version 2.
Since the tool can support now API version 3, update the supported API
version.

When core-power configuration or enabled is modified, this is only done
for compute dies. But the config must also be set to cores with no CPUs.
Without this the configuration is not affective.
On displaying config information, allow display for non compute dies
also.

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.
