arm: mvebu: Enable USB EHCI support on Armada XP
This patch enables the USB EHCI support for the Marvell Armada XP (AXP) SoCs. In compatism to the Armada 38x (A38x), the AXP needs to configure the USB PLL and the USB PHY's specifically in U-Boot. The A38x has done this already in the bin_hdr (SPL U-Boot). Without this, accessing the controller registers in U-Boot or Linux will hang the CPU. Additionally, the AXP uses a different USB EHCI base address. This patch also takes care of this by runtime SoC detection in the Marvell EHCI driver.
