Subject: net: phy: make .ack_interrupt() optional

As a first step into making phylib and all PHY drivers to actually
have support for shared IRQs, make the .ack_interrupt() callback
optional.

After all drivers have been moved to implement the generic
interrupt handle, the phy_drv_supports_irq() check will be
changed again to only require the .handle_interrupts() callback.
