platform/x86/intel/vsec: Support private data

Add fields to struct intel_vsec_device, so that core module (which
creates aux bus devices) can pass private data to the client drivers.

For example there is one vsec device instance per CPU package. On a
multi package system, this private data can be used to pass the package
ID. This package id can be used by client drivers to change power
settings for a specific CPU package by targeting MMIO space of the
correct PCI device.
