PXA25X chips don't support alternate settings so code in ether.c disables usage of CDC. But only code defined between DEV_CONFIG_CDC signals that network is up. This patch is fixing this bug by addding pxa_connect_gadget() which on pxa25x chips signals that network is up and do nothing on any other chips.
