DRIVERS: USB: Initialize HSIC PHYs and enable 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 initializes the HSIC PHYs, performs reset sequence for USB3503 hub and enables the relevant config options for network to work. Signed-off-by: Inderpal Singh <inderpal.singh@linaro.org>
