[PATCH net-next v2 1/2] net: phy: replace PHY_HAS_INTERRUPT with a check for config_intr and ack_interrupt

[Heiner Kallweit]

Flag PHY_HAS_INTERRUPT is used only here for this small check. I think
using interrupts isn't possible if a driver defines neither
config_intr nor ack_interrupts callback. So we can replace checking
flag PHY_HAS_INTERRUPT with checking for these callbacks.

v2:
- add helper for the check
