[PATCH V2 02/15] platform/x86/intel/vsec: Add private data for per-device data

[David E. Box]

Introduce a new private structure, struct vsec_priv, to hold a pointer to
the platform-specific information. Although the driver didn’t previously
require this per-device data, adding it now lays the groundwork for
upcoming patches that will manage such data. No functional changes.
