I've tried this series on my vim3l with the this driver compiled as a
module, and lost the Ethernet interface in the process, as the phy
wasn't able to resolve its interrupt and things fail later on:
[ 72.238291] meson8b-dwmac ff3f0000.ethernet eth1: no phy at addr -1
[ 72.238917] meson8b-dwmac ff3f0000.ethernet eth1: stmmac_open: Cannot attach to PHY (error: -19)
This is a generic problem with making DT-based interrupt controllers
modular when not *all* the drivers can deal with probing deferral.
