Subject: [PATCH] ARM: ep93xx: Avoid soc_device_to_device()

ep93xx_init_soc() uses soc_device_to_device() to return a device
to ep93xx_init_devices(), where it is passed on to its callers,
who all ignore the return value. As this helper is deprecated,
change the return type of ep93xx_init_devices() to void and
have ep93xx_init_soc() return the soc_device instead.
