161ae6b04d net: dsa: lan9303: make functions lan9303_mdio_phy_{read|write} static
The functions lan9303_mdio_phy_write and lan9303_mdio_phy_read are local
to the source and do not need to be in global scope, so make them static.

Cleans up sparse warnings:
symbol 'lan9303_mdio_phy_write' was not declared. Should it be static?
symbol 'lan9303_mdio_phy_read' was not declared. Should it be static?

2c3408986c net: dsa: lan9303: MDIO access phy registers directly
Indirect access (PMI) to phy register only work in I2C mode. In
MDIO mode phy registers must be accessed directly. Introduced
struct lan9303_phy_ops to handle the two modes.

dc70058315 net: dsa: LAN9303: add MDIO managed mode support
When the LAN9303 device is in MDIO manged mode, all register accesses must
be done via MDIO.

Please note: this code is compile time tested only due to the absence of such
configured hardware. It is based on a patch from Stefan Roese from 2014.
