This implements a MemoryInitPeiLib instance that differs from the stock ArmPlatformPkg version only in the fact that it does not remove the memory used by the flash device (FD). The reason is that, when using PrePi, the DXE core is started immediately and never returns so there is no reason to preserve any of the memory that the flash device occupied originally, and it is preferable to release is so that the OS loader can reuse it. This is especially important for the relocatable PrePi configuration, which is aimed at being launched from a boot loader that itself adheres to the Linux arm64 boot protocol.
