There are two PCB designs in the wild which use the opposite signaling for SD card detection. This makes U-Boot working in one case and failing in the other. Quirk this out by disconnecting SD card detection pin from the PCB by switching it to mode 3. In the disconnected state the read value is always the same and inverted to what we are expecting in the code.
