[PATCH -next] net: pcs: pcs-xpcs: Fix build error when CONFIG_PCS_XPCS=y && CONFIG_PHYLINK=m

[Zheng Bin]

If CONFIG_PCS_XPCS=y, CONFIG_PHYLINK=m, bulding fails:

drivers/net/pcs/pcs-xpcs.o: in function `xpcs_do_config':
pcs-xpcs.c:(.text+0x64f): undefined reference to `phylink_mii_c22_pcs_encode_advertisement'
drivers/net/pcs/pcs-xpcs.o: in function `xpcs_get_state':
pcs-xpcs.c:(.text+0x10f8): undefined reference to `phylink_mii_c22_pcs_decode_state

Make PCS_XPCS depends on PHYLINK to fix this.
