dm: ns16550: Use an address instead of a pointer for the uart base
It is inconvenient to have to use casts when specifying platform data. Also it is not strictly correct, since we should use map_sysmem() to convert an address to a pointer. Adjust the platform data to use an address. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@ti.com>
