ARM: 7519/1: integrator: convert platform devices to Device Tree
This moves the physmap flash and SMSC91x ethernet devices over to the device tree, moving the static board code down into the #ifndef CONFIG_OF section. Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
