[PATCH] ppc32 CPM_UART: Convert to use platform devices

Browse Source 
This is intended to make the driver code more generic and flexible,
to get rid of board-specific layouts within driver, and generic rehaul,
yet keeping compatibility with the existing stuff utilizing it, being
compatible with legacy behavior (but with complaints that legacy mode
used).
