net: phy: allow for reset line to be tied to a sleepy GPIO controller
mdio_device_reset() makes use of the atomic-pretending API flavor for handling the PHY reset GPIO line. I found no hint that mdio_device_reset() is called from atomic context and indeed it uses usleep_range() since long time, so I would assume that it is OK to sleep there. This patch switch to gpiod_set_value_cansleep() in mdio_device_reset(). This is relevant if e.g. the PHY reset line is tied to a I2C GPIO controller. This has been tested on a ZynqMP board running an upstream 4.19 kernel and then hand-ported on current kernel tree.
