x86/efi: Implement a __efi_call_virt macro
For i386, all the EFI system runtime services functions return efi_status_t except efi_reset_system_system. Therefore, not all functions can be covered by the same macro in case the macro needs to do more than calling the function (i.e., return a value). The purpose of the __efi_call_virt macro is to be used when no return value is expected. For x86_64, this macro would not be needed as all the runtime services return u64. However, the same code is used for both x86_64 and i386. Thus, the macro __efi_call_virt is also defined to not break compilation.
