arm: mvebu: Add Armada 38x SERDES / PHY init code from Marvell bin_hdr

This code is ported from the Marvell bin_hdr code into mainline
SPL U-Boot. It needs to be executed very early so that the devices
connected to the serdes PHY are configured correctly.

+ *       bus      - PEX segment bus number.

+ *       func     - Function number.
+ *       reg_offs - Register offset.
+ *
+ * OUTPUT:
+ *       None.
