net: phy: marvell-88q2xxx: Fix temperature measurement with reset-gpios
[ Upstream commit a197004cf3c2e6c8cc0695c787a97e62e3229754 ]
When using temperature measurement on Marvell 88Q2XXX devices and the
reset-gpios property is set in DT, the device does a hardware reset when
interface is brought down and up again. That means that the content of
the register MDIO_MMD_PCS_MV_TEMP_SENSOR2 is reset to default and that
leads to permanent deactivation of the temperature measurement, because
activation is done in mv88q2xxx_probe. To fix this move activation of
temperature measurement to mv88q222x_config_init.
Fixes: a557a92e6881 ("net: phy: marvell-88q2xxx: add support for temperature sensor")
