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.
Fixes: 0d2e778e38e0 ("net: phy: replace PHY_HAS_INTERRUPT with a check for config_intr and ack_interrupt")
