NET: LAN91C96 CONFIG_NET_MULTIify

Make the lan91c96 driver capable of CONFIG_NET_MULTI
to be clean for the new arch, add a a lil detect function
Most of the formatting change was done to keep checkpatch
silent, but a few functions and #if 0ed code which
does not make sense for NET_MULTI have been removed

Now, use the lan91c96_initialize() function to init the driver
