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.
