sh-pfc: Drop unused support for 1:1 physical to virtual memory mappings
Now that all PFC platform devices provide memory resources support for registers without an associated memory resource isn't used anymore. Drop it. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Acked-by: Linus Walleij <linus.walleij@linaro.org>
