There are 2 ways an EFI payload could return into u-boot:
- Callback function
- Exception
While in EFI payload mode, x18 is owned by the payload and may not contain
a valid pointer to gd, so we need to fix it up. We do that properly for the
payload to callback path already.
This patch also adds gd pointer restoral for the exception path.
