net: dsa: bcm_sf2: Clear IDDQ_GLOBAL_PWR bit for PHY
The PHY on BCM7278 has an additional bit that needs to be cleared:
IDDQ_GLOBAL_PWR, without doing this, the PHY remains stuck in reset out
of suspend/resume cycles.
Fixes: 0fe9933804eb ("net: dsa: bcm_sf2: Add support for BCM7278 integrated switch")
