net: pcs: xpcs: depends on PHYLINK in Kconfig

This is yet 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!

Switch XPCS to be invisible, as Russell points out it's
"selected" by its consumers. Drop the dependency on MDIO_BUS
as "depends" is meaningless on "selected" symbols.
