[RFC PATCH u-boot 04/12] efi_loader: fix warning when linking with LTO

[Marek Behún]

When linking with LTO, the compiler complains about type mismatch of
variables `__efi_runtime_start`, `__efi_runtime_stop`,
`__efi_runtime_rel_start` and `__efi_runtime_rel_stop`:

 include/efi_loader.h:218:21: warning: type of ‘__efi_runtime_start’
                                       does not match original
                                       declaration [-Wlto-type-mismatch]
   218 | extern unsigned int __efi_runtime_start, __efi_runtime_stop;
        |                     ^
  arch/sandbox/lib/sections.c:7:6: note: ‘__efi_runtime_start’ was
                                         previously declared here
      7 | char __efi_runtime_start[0] __attribute__((section(".__efi_runtime_start")));
        |      ^

Change the type to char[] in include/efi_loader.h.
