[U-Boot] [PATCH 1/3] usbether: Fixed bug when using with PXA25X chips

[Łukasz Dałek]

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.
