[PATCH v3 2/2] net: phy: call phy_disable_interrupts() in phy_init_hw()

[Jisheng Zhang]

Call phy_disable_interrupts() in phy_init_hw() to "have a defined init
state as we don't know in which state the PHY is if the PHY driver is
loaded. We shouldn't assume that it's the chip power-on defaults, BIOS
or boot loader could have changed this. Or in case of dual-boot
systems the other OS could leave the PHY in whatever state." as pointed
out by Heiner.
