Arndale board has AX88760, which is USB 2.0 Hub & USB 2.0 Ethernet Combo controller, connected to HSIC Phy of USB host controller via USB3503 hub.
This patch implements a board specific board_usb_init function in ehci driver to perform reset sequence for USB3503 hub and enables the relevant config options for network to work.
