Subject: [PATCH net-next] net: pcs: xpcs: depends on PHYLINK in Kconfig

This is another attempt at fixing:

>> ERROR: modpost: "phylink_mii_c22_pcs_encode_advertisement" [drivers/net/pcs/pcs_xpcs.ko] undefined!
>> ERROR: modpost: "phylink_mii_c22_pcs_decode_state" [drivers/net/pcs/pcs_xpcs.ko] undefined!

We can't select PHYLINK, or that will trigger a circular dependency
PHYLINK already selects PHYLIB, which in turn selects MDIO_DEVICE:
replacing the MDIO_DEVICE dependency with PHYLINK will pull all the
required configs.
