[PATCH] net: dsa: bcm_sf2: Clear IDDQ_GLOBAL_PWR bit for PHY

[Florian Fainelli]

From: Florian Fainelli <florian.faine...@broadcom.com>

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.

refs #SWLINUX-4599

Fixes: 1ad948be42b4 ("net: dsa: bcm_sf2: Add support for BCM7278 integrated 
switch")
