[PATCH 2/6] qemu: domain: Store virStorageSources representing pflash backing

[Peter Krempa <pkrempa@xxxxxxxxxx>]

To allow converting the pflash drives to blockdev we will need a
virStorageSource to allow using our helpers. Temporarily prior to
coverting loader data to a virStorageSoruce add private data which will
house this.
