The mdio driver currently initializes the phy polling registers
with some nasty magic. It identifies the interface mode from the
dts and draws some strange conclusions.
Looking at the SDK one can see that this is basically dependent
of the attached phy type. So the code location is quite right
inside the mdio driver.
Provide a new get_phy_info() function that determines the phy
characteristics that are important for the polling unit . It will
be later needed by the RTL93xx setup code.
Some explanation about the fields of the structure:
- has_res_reg: phy has a special Realtek resolution polling
register. It is unclear if this gives more details or if it
simply allows faster polling.
- has_giga_lite: This is a phy that allows for Realtek proprietary
1G/2.5G lite connectivity. In this case data is only transmitted
over two wire pairs.
