Subject: [Patch net-next 07/11] net: dsa: microchip: get P_STP_CTRL in ksz_port_stp_state by ksz_dev_ops
At present, P_STP_CTRL register value is passed as parameter to
ksz_port_stp_state from the individual dsa_switch_ops hooks. This patch
update the function to retrieve the register value through the
ksz_chip_data member.
And add the static to ksz_update_port_member since it is not called
outside the ksz_common.
