Instead of using hardcoded base addresses implicitly obtained through <linux/io.h>, pass the physical base for the three NPE blocks as memory resources and remap these in the driver. Drop the memory request region business, this will anyways be done by devm_* remapping functions. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
