lan9303_enable_packet_processing, lan9303_disable_packet_processing()
Pass port number (0,1,2) as parameter instead of port offset.
Because other functions in the module pass port numbers.
And to enable simplifications in following patch.
Introduce lan9303_write_switch_port().

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.

Preparing for the following fix of MDIO phy access:
Renamed functions that access PHY 1 and 2 indirectly through PMI
registers.
lan9303_port_phy_reg_wait_for_completion() to
lan9303_indirect_phy_wait_for_completion()
lan9303_port_phy_reg_read() to
lan9303_indirect_phy_read()
lan9303_port_phy_reg_write() to
lan9303_indirect_phy_write()
Also changed "val" parameter of lan9303_indirect_phy_write() to u16,
for clarity.

The current dsa_register_switch function takes a useless struct device
pointer argument, which always equals ds->dev.
Drivers either call it with ds->dev, or with the same device pointer
passed to dsa_switch_alloc, which ends up being assigned to ds->dev.
This patch removes the second argument of the dsa_register_switch and
_dsa_register_switch functions.

The SMSC/Microchip LAN9303 is an ethernet switch device with one CPU port
and two external ethernet ports with built-in phys.
This driver uses the DSA framework, but is currently only capable of
separating the two external ports. There is no offload support yet.
