However DM_FLAG_PRE_RELOC is a driver - and not a device - flag. This means that the check in pre_reloc_only mode would always fail. Instead, what was aimed to be checked is that either the driver of the device has the flag set, or that the device has the u-boot,dm-pre-reloc Device Tree property set. So let's fix the check to allow u-boot,dm-pre-reloc devices to be probed.
