[PATCH v2 net-next] net: phy: improve struct phy_device member interrupts handling

[Heiner Kallweit]

As a heritage from the very early days of phylib member interrupts is
defined as u32 even though it's just a flag whether interrupts are
enabled. So we can change it to a bitfield member. In addition change
the code dealing with this member in a way that it's clear we're
dealing with a bool value.

v2:
- use false/true instead of 0/1 for the constants

Actually this member isn't needed at all and could be replaced with
a parameter in phy_driver->config_intr. But this would mean an API
change, maybe I come up with a proposal later.
