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.
