The newly introduced regmap-based MDIO driver allows for an easy mapping

Lynx PCS.

Convert Altera TSE to use this PCS instead of the pcs-altera-tse, which
is nothing more than a memory-mapped Lynx PCS.

It turns out I'm missing the zeroing of pcs_regmap_cfg, which can trigger
errors at probe time. I know this series has been applied, and that I can
send a followup fix, but due to the missing regmap patch in the net-next
tree, this series will break altera_tse and dwmac_socfpga anyway,as
mentionned here (and in the cover):

Is reverting the way to go then ?
