Maybe we should just set the sleep state in remove and leave it out of the
phy functions. If a separate state is needed for the phy_mdm6600_power_off(),
it could be the pinctrl idle state.

We need the reset pin in probe to get the modem started. The modem may
also be started in uart mode for firmware flashing depending on how the
gpio pins are set.
