net: phy: icplus: add config_intr callback
Move IRQ configuration for IP101A/G from config_init to config_intr
callback. Reasons:
1. This allows phylib to disable interrupts if needed.
2. Icplus was the only driver supporting interrupts w/o defining a
config_intr callback. Now we can add a phylib plausibility check
disabling interrupt mode if one of the two irq-related callbacks
isn't defined.
I don't own hardware with this PHY, and the change is based on the
datasheet for IP101A LF (which is supposed to be register-compatible
with IP101A/G). Change is compile-tested only.
