shows following warning:

commit  0f8cbc1829d9c7d9616fd29b366a99d037facdcd

Do not init SATA when disabled on 8536DS.

SGMII and SATA share the serdes on MPC8536 CPU, When SATA disabled and the
driver still try to access the SATA registers, the cpu will hangup.
This patch try to fix this by reading the serdes status before the SATA
initialize.
