Telemetry platform driver implements the telemetry interfaces.
Currently it supports ApolloLake. It uses the PUNIT and PMC IPC
interfaces to configure the telemetry samples to read.
The samples are read from a Secure SRAM region.

Intel PM Telemetry is a software mechanism via which various SoC
PM and performance related parameters like PM counters, firmware
trace verbosity, the status of different devices inside the SoC, etc
can be monitored and analyzed. The different samples that may be
monitored can be configured at runt
