net: phy: realtek: Dummy IRQ calls for RTL8366RB
This fixes a regression introduced by commit 0d2e778e38e0ddffab4bb2b0e9ed2ad5165c4bf7 "net: phy: replace PHY_HAS_INTERRUPT with a check for config_intr and ack_interrupt". This assumes that a PHY cannot trigger interrupt unless it has .config_intr() or .ack_interrupt() implemented. A later patch makes the code assume both need to be implemented for interrupts to be present. But this PHY (which is inside a DSA) will happily fire interrupts without either callback. Implement dummy callbacks for .config_intr() and .ack_interrupt() in the phy header to fix this. Tested on the RTL8366RB on D-Link DIR-685.
