This patch is to enable Intel SERDES power up/down sequence. The SERDES
converts 8/10 bits data to SGMII signal.

1. Two new files intel_serdes.c and intel.h have been created to include
the power up/down logic.

2. Platform data has_serdes is created to identify HW system that requires
SERDES for SGMII mode. Expecting all Intel HW system will require it.
The identification logic is added in hwif.

3. A new stmmac_serdes_ops struct is introduced as helpers to program
SERDES.
