[U-Boot] [PATCH 1/3] zynq: Add EFI runtime sections to linker script

When using EFI_LOADER, we add a few special sections for runtime code and
data which get relocated on demand when executing a target OS.

These runtime structures need to get annotated properly in the linker script.
While we do that properly in the generic one, we missed out on the zynq
specific linker script.

This patch adds the EFI runtime section annotations into the zynq linker script
so that the efi loader code actually works on that platform.
