This patch adds TSE PCS support to existing dwmac-socfpga.c and designware.c,
which adds a new file net/phy/altr_tse_pcs.c, while dwmac-socfpga.c and
designware.c call its functions. Hence, I didn't split this implementation into several
patches because I didn't want net/phy/altr_tse_pcs.c to appear like a dead code.

If it's confusing, I could rename altr_tse_pcs.c to altr_dwmac_pcs.c, since it is
under DWMAC SGMII.
