[PATCH v4 36/38] platform/x86: intel_telemetry: Add telemetry_get_pltdata()

[Mika Westerberg <mika.westerberg@linux.intel.com>]

Add new function that allows telemetry modules to get pointer to the
platform specific configuration. This is needed to allow the telemetry
debugfs module to fetch PMC IPC instance in the subsequent patch.
