usb: exynos5: arndale: Add network support
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 uses board specific board_usb_init function to perform reset sequence for USB3503 hub and enables the relevant config options for network to work.
