Subject: [PATCH net-next v2 1/3] net: altera-tse: Initialize the regmap_config struct before using it

The regmap_config needs to be zeroed before using it. 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")
