[PATCH net] net: dsa: remove phy.h and phy_fixed.h inclusions

[Florian Fainelli <f.fainelli@gmail.com>]

There is no need to include phy.h nor phy_fixed.h when we can use
forward declarations instead to keep the include chain smaller.

Doing this unveiled that we were implicitely getting the definitions for
struct ethtool_eee and struct ethtool_wolinfo, and that net/dsa/slave.c
was missing an include of phy_fixed.h.

Fixes: ec9436baedb6 ("net: dsa: allow drivers to do link adjustment")
Fixes: ce31b31c68e7 ("net: dsa: allow updating fixed PHY link information")
