ReserveEmuVariableNvStore is updated with below 2 functions defined in PlatformInitLib: - PlatformReserveEmuVariableNvStore - PlatformInitEmuVariableNvStore PlatformInitEmuVariableNvStore works when secure boot feature is enabled. This is because secure boot needs the EFI variables (PK/KEK/DB/DBX, etc) and EmuVariableNvStore is cleared when OVMF is launched with -bios parameter.
