The GENI SE QUP wrapper driver (geni-se-qup) needs to be bound during pre-relocation to allow its child devices (such as the debug UART) to be discovered and probed before relocation.
Without DM_FLAG_PRE_RELOC, the qupv3 device is skipped during the pre-relocation DM scan, which prevents early serial devices from being bound. This causes serial_find_console_or_panic() to fail with "No serial driver found" during serial_init(). Add DM_FLAG_PRE_RELOC to the geni_se_qup driver so that the GENI SE QUP wrapper and its children are bound during pre-relocation, enabling the serial console to be initialized correctly.
