Fix breakage in SMC EEPROM standalone applications

Commit 6a45e384 (Make getenv_IPaddr() global)
inadvertently added ' #include "net.h" ' to the standalone programs, creating
duplicate definitions of 'struct eth_device'.  This patch removes the local
definitions and removes other code that breaks due to the change in definition.
