Srinivas Pandruvada ea009e4769 platform/x86: ISST: Add SST-PP support via TPMI
This Intel Speed Select Technology - Performance Profile (SST-PP) feature
introduces a mechanism that allows multiple optimized performance profiles
per system. Each profile defines a set of CPUs that need to be online and
rest offline to sustain a guaranteed base frequency.

Five new IOCTLs are added:
ISST_IF_PERF_LEVELS : Get number of performance levels
ISST_IF_PERF_SET_LEVEL : Set to a new performance level
ISST_IF_PERF_SET_FEATURE : Activate SST-BF/SST-TF for a performance level
ISST_IF_GET_PERF_LEVEL_INFO : Get parameters for a performance level
ISST_IF_GET_PERF_LEVEL_CPU_MASK : Get CPU mask for a performance level

Once an instance is identified, read or write from correct MMIO
offset for a given field as defined in the specification.

For details on SST PP operations using intel-speed-selet utility,
refer to:
