This is a small NET_LWIP cleanup. Instead of re-creating a struct netif
from a struct udevice every time a nework operation is requested (dhcp,
ping, etc.), store the netif inside the udevice.

No functional change is expected, but the behavior of the network stack
might change a bit since not removing the device may have impacts on
various states in the stack (the ARP cache for instance).

Jerome Forissier (3):
  dm: core: add 'netif' field to struct udevice for NET_LWIP
  net: lwip: save struct netif in struct udevice
  net: lwip: remove net_lwip_remove_netif()
