Subject: include/efi: Introduce __efiapi for EFI calling convention
 flexibility

This patch defines __efiapi (based on EFIAPI) for coreboot-compliant
EFI calls. This lays the groundwork for future 64-bit EFI calling
convention support within coreboot/FSP.

BUG=b:242829490
TEST=FSP debug log accessible via coreboot event handler.
