[PATCH 6.1.y 1/4] platform/x86/intel/vsec: Add private data for per-device data

[Sasha Levin <sashal@kernel.org>]

From: "David E. Box" <david.e.box@linux.intel.com>

[ Upstream commit dc957ab6aa05c118c3da0542428a4d6602aa2d2d ]

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.
