Add support for exynos5_ehci in loader

[wma_semihalf.com]

Summary

Add all missing functionality to allow runing Exynos5 EHCI controller inside loader.

Any user application (including loader) should provide three callbacks for allocating resources & ofw parsing:
extern int (*bus_alloc_resource_any_cb)(struct resource *res, device_t dev,

int type, int *rid, unsigned int flags);

extern int (*ofw_bus_status_ok_cb)(device_t dev);
extern int (*ofw_bus_is_compatible_cb)(device_t dev, char *name);

Why are you accessing this directly, and not through the U-Boot API?

The goal for this thing is to have the USB controller (sys/boot/usb & sys/boot/kshim library) independent of u-boot.

I think it should be possible to remove this first check. Can you run a test only replacing "mod->mod_name" with "mod->driver->name" ?

Removed the first check.
