Add PcdEmuVariableNvStoreReserved which allows a platform to declare a memory address for the EMU Variable driver to use for the NV variable store. The EMU Variable driver will look to see if the contents of this memory range appear to be a valid variable store, and if so the EMU driver will use the variables. If a platform can preserve a memory range across system resets, this feature can allow the EMU Variable driver's NV variable store to be preserved across a system reset. In the default case this PCD will be set as a fixed PCD with a value of 0. In this case this new feature should have minimal impact on the EMU Variable driver. (Perhaps a slight increase in code size, but no functional difference is expected.) git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@9240 6f19259b-4bc3-4df7-8a09-765794883524
