[PATCH v2 0/2] Add EDKII_PCI_DEVICE_PPI support to EDK2

["Maciej Czajkowski" <maciej.czajkowski@intel.com>]

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3907

The purpose of those changes is to introduce the way to enumerate and assign resources in PEI for the systems with more than one PCI root. 
Here is a need to have an interface that will support such a mechanizm.
For now, the part that performs the enumeration will be implemented in the silicon code.
Sample code can be seen here: https://github.com/mczaj/edk2-platforms/commit/d443062e58f9fba228869b54f2546d9735b3b506
