efi_loader: discover if no efi_system_partition is set
Variable efi_system_partition holds the efi_system_partition. Currently it is initialized as: { .uclass_id = 0 = UCLASS_ROOT, .denum = 0, .part = 0, } This indicates that host 0:0 is the efi_system_partition and we see output like: => bootefi hello ** Bad device specification host 0 ** Couldn't find partition host 0:0 To identify that no EFI system partition has been set use UCLASS_INVALID.
