The KS8695 device.c provides registration functionality for the KS8695's various devices such as watchdog timers and ethernet devices. Rather than predicating those on the config options for the drivers, always register the platform devices so that a later built module can hook on. Also, the ethernet used to register virtual addresses in the platform data. This is wrong and so this patch changes them to physical addresses and also passes in the appropriate physical region for the PHY or Switch as appropriate.
