The rut955 fails to activate its modem upon every second reboot otherwise.
This will issue reset every time the qmi connection is (re-)initialized,
making the whole (re-)connection process much longer. Does the modem
really need to be reset every time the connection is brought up or just
once, after the bootup?
IIRC, RUT9xx series has a dedicated GPIO for modem power enable/disable.
How about using that instead?
