net: wangxun: move PHYLINK dependency

The LIBWX library code is what calls into phylink, so any user of
it has to select CONFIG_PHYLINK at the moment, with NGBEVF missing this:

x86_64-linux-ld: drivers/net/ethernet/wangxun/libwx/wx_ethtool.o: in function `wx_nway_reset':
wx_ethtool.c:(.text+0x613): undefined reference to `phylink_ethtool_nway_reset'
x86_64-linux-ld: drivers/net/ethernet/wangxun/libwx/wx_ethtool.o: in function `wx_get_link_ksettings':
wx_ethtool.c:(.text+0x62b): undefined reference to `phylink_ethtool_ksettings_get'
x86_64-linux-ld: drivers/net/ethernet/wangxun/libwx/wx_ethtool.o: in function `wx_set_link_ksettings':
wx_ethtool.c:(.text+0x643): undefined reference to `phylink_ethtool_ksettings_set'
x86_64-linux-ld: drivers/net/ethernet/wangxun/libwx/wx_ethtool.o: in function `wx_get_pauseparam':
wx_ethtool.c:(.text+0x65b): undefined reference to `phylink_ethtool_get_pauseparam'
x86_64-linux-ld: drivers/net/ethernet/wangxun/libwx/wx_ethtool.o: in function `wx_set_pauseparam':
wx_ethtool.c:(.text+0x677): undefined reference to `phylink_ethtool_set_pauseparam'

Add the 'select PHYLINK' line in the libwx option directly so this will
always be enabled for all current and future wangxun drivers, and remove
the now duplicate lines.
