[PATCH net-next v4 1/5] net: altera-tse: Initialize local structs before using it

[Maxime Chevallier]

The regmap_config and mdio_regmap_config objects needs to be zeroed before
using them. This will cause spurious errors at probe time as config->pad_bits
is containing random uninitialized data.

Fixes: db48abbaa18e ("net: ethernet: altera-tse: Convert to mdio-regmap and use PCS Lynx")
