The newly introduced function is only used inside of an #ifdef
and causes a warning when that is disabled:

drivers/net/dsa/mv88e6xxx/chip.c:4623:13: error: unused function 'mv88e6xxx_ports_cmode_init' [-Werror,-Wunused-function]

Move it into the same #ifdef block to shut up the warning.

Fixes: ed8fe20205ac ("net: dsa: mv88e6xxx: prevent interrupt storm caused by mv88e6390x_port_set_cmode")
