[PATCH] yenta: make bridge specific init code configurable

Browse Source 
Make the bridge specific initialization code config options depending on
CONFIG_EMBEDDED. Config options for TI/EnE, Toshiba, Ricoh and O2Micro are
available. Disabling all of the specific tweaks cuts off more than half
of yenta_socket.ko.
