Subject: [PATCH RFC net-next v4 10/14] net: stmmac: move dwmac_ctrl_ane() into
stmmac_pcs.c
Move dwmac_ctrl_ane() into stmmac_pcs.c, changing its arguments to take
the stmmac_priv structure. Update it to use the previously provided
__dwmac_ctrl_ane() function, which makes use of the stmmac_pcs struct
and thus does not require passing the PCS base address offset.
This removes the core-specific functions, instead pointing the method
at the generic method in stmmac_pcs.c.
