CONFIG_USB_HSIC_USB3503 is needed by exynos5250-arndale for the on-board
asix network controller. Enable it so networking works with
multi_v7_defconfig out of box like it does with exynos_defconfig.

USB3503 is also referenced from exynos4412-odroidu3.dts and
exynos5250-spring.dts so this patch should improve
multi_v7_defconfig on those platforms as well.

Is someone looking into fixing it? Having to load this as module would
be an inconvenience for me, as I like to boot arndale with nfsroot.
Yet I understand that eventually I'll need to use an initrd - so not a
blocker, just grumpy work.
