net: bcmgenet: Remove excessive PHY reset
We are currently issuing multiple PHY resets during a suspend/resume,
first during bcmgenet_power_up() which does a hardware reset, then a
software reset by calling bcmgenet_mii_reset(). This is both unnecessary
and can take as long as 10ms per MDIO transactions while we re-apply
workarounds because we do not yet have MDIO interrupts enabled.
phy_resume() takes care of re-apply our workarounds in case we need any,
and bcmgenet_power_up() does a PHY hardware reset, all of this is more
than enough to guarantee that the PHY operates correctly.
Fixes: 1c1008c793fa4 ("net: bcmgenet: add main driver file")
