net: dsa: mv88e6xxx: force cmode write on 6141/6341
mv88e6xxx_port_set_cmode() relies on cmode stored in struct mv88e6xxx_port to skip cmode update when the requested value matches the cached value. It turns out that mv88e6xxx_port_hidden_write() might change the port cmode setting as a side effect, so we can't rely on the cached value to determine that cmode update in not necessary. Force cmode update in mv88e6341_port_set_cmode(), to make serdes configuration work again. Other mv88e6xxx_port_set_cmode() callers keep the current behaviour. This fixes serdes configuration of the 6141 switch on SolidRun Clearfog GT-8K.
