qualcommax: dwmac-ipq5018: support the kernel 6.18 stmmac API

The fix_mac_speed() callback takes the speed as an int on 6.18
(SPEED_UNKNOWN is negative); it was unsigned int on 6.12. Select the
prototype on LINUX_VERSION_CODE so the driver keeps building on the 6.12
main kernel and on the 6.18 testing kernel.
