When built in, GENI I2C can request serial-engine firmware during
probe. If initramfs unpacking is still in progress, request_firmware()
waits for it to complete, blocking subsequent driver initialization.
Prefer asynchronous probing so that other drivers can initialize in
parallel while the firmware request waits for initramfs unpacking.
