efi: efi-iomem: don't add EFI loader code/data as memory banks
The loader code and data memory descriptors describe code used by the
currently running barebox instance. This is already used memory, so
registering it as available SDRAM is wrong. Instead, just reserve the
IO MEM region for informational purposes.
