ARM: at91: move platform_data definitions
Platform data for device drivers should be defined in include/linux/platform_data/*.h, not in the architecture and platform specific directories. This moves such data out of the at91 include directories Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Acked-by: Nicolas Pitre <nico@linaro.org> Acked-by: Nicolas Ferre <nicolas.ferre@atmel.com> Acked-by: Vinod Koul <vinod.koul@linux.intel.com> Cc: Jean-Christophe Plagniol-Villard <plagnioj@jcrosoft.com> Cc: Dan Williams <djbw@fb.com>
