[PATCH V4 02/17] platform/x86/intel/vsec: remove platform_info from vsec device structure

["David E. Box" <david.e.box@linux.intel.com>]

In preparation for exporting an API to register Intel Vendor Specific
Extended Capabilities (VSEC) from other drivers, remove the pointer to
platform_info from intel_vsec_device. This prevents a potential page fault
when auxiliary drivers probe and attempt to dereference this pointer to
access the needed quirks field. Instead, just add the quirks to
intel_vsec_device.
