mpc83xx: initialize serdes for MPC837xEMDS boards

Browse Source 
This patch is stolen from Anton Vorontsov's patch
for mpc837xerdb boards.

The reference clk and xcorevdd voltage of serdes1/2
is same between mpc837xemds and mpc837xerdb.

8377E: LYNX1- 2 SATA	LYNX2- 2 PCIE
8378E: LYNX1- 2 SGMII	LYNX2- 2 PCIE
8379E: LYNX1- 2 SATA	LYNX2- 2 SATA
