Subject: [PATCH] Revert "PPP: restore PPPoE devices without Ethernet ARP
 support, i.e. PPPoE only devices"

This reverts commit d43c092f171e683028e184af56333dab9ce79fcb.

We don't actually need it, init.c is including ppp_opts.h and is doing
the following:

  #if !LWIP_ETHERNET && (LWIP_ARP || PPPOE_SUPPORT)
    #error "LWIP_ETHERNET needs to be turned on for LWIP_ARP or PPPOE_SUPPORT"
  #endif

so the LWIP_ETHERNET fixup is not necessary per se, compatibility with
previously used lwipopts.h files is broken but at least user is warned.
