[U-Boot] [PATCH v2 06/11] 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.

Changes in v2: None
