ipq40xx: abort ar40xx probe on missing PHYs

The ar40xx driver currently panics in case no QCA807x PHY has been
successfully probed. This happens when the external PHY is still
in reset when probing the ar40xx switch driver.

Note that this patch does not fix the root cause, ar40xx_probe now
simply fails instead of causing a kernel panic due to a nullpointer
dereference.
