Srinivas Pandruvada d805456c71 platform/x86: ISST: Enumerate TPMI SST and create framework 
Enumerate TPMI SST driver and create basic framework to add more
features.

The basic user space interface is still same as the legacy using
/dev/isst_interface. Users of "intel-speed-select" utility should
be able to use same commands as prior gens without being aware
of new underlying hardware interface.

TPMI SST driver enumerates on device "intel_vsec.tpmi-sst". Since there
can be multiple instances and there is one common SST core, split
implementation into two parts: A common core part and an enumeration
part. The enumeration driver is loaded for each device instance and
register with the TPMI SST core driver.

On very first enumeration the TPMI SST core driver register with SST
core driver to get IOCTL callbacks. The api_version is incremented
for IOCTL ISST_IF_GET_PLATFORM_INFO, so that user space can issue
new IOCTLs.

Each TPMI package contains multiple power domains. Each power domain
has its own set of SST controls. For each domain map the MMIO memory
and update per domain struct tpmi_per_power_domain_info. This information
will be used to implement other SST interfaces.

Implement first IOCTL commands to get number of TPMI SST instances
and instance mask as some of the power domains may not have any
SST controls.
