"Platform.h" declares the AmdSevInitialize() function without EFIAPI, but the definition in "AmdSev.c" includes EFIAPI. GCC toolchains without LTO do not catch this error because "AmdSev.c" does not include "Platform.h"; i.e. the declaration used by callers such as "Platform.c" is not actually matched against the function definition at build time. With LTO enabled, the mismatch is found -- however, as a warning only, due to commitf8d0b96629
("BaseTools GCC5: disable warnings-as-errors for now", 2016-08-03). Include the header in the C file (which turns the issue into a hard build error on all GCC toolchains), plus sync the declaration from the header file to the C file. There's been no functional breakage because AmdSevInitialize() takes no parameters.
