pcmcia: use pcmcia_loop_config in misc pcmcia drivers

Browse source 
Use pcmcia_loop_config() in a few drivers missed during the first
round. On fmvj18x_cs.c it -- strangely -- only requries us to set
conf.ConfigIndex, which is done by the core, so include an empty
loop function which returns 0 unconditionally.
