ARM: davinci: 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 davinci 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: Mauro Carvalho Chehab <mchehab@redhat.com> Acked-by: Felipe Balbi <balbi@ti.com> Cc: Sekhar Nori <nsekhar@ti.com> Cc: Kevin Hilman <khilman@ti.com> Cc: "Ben Dooks" <ben-linux@fluff.org> Cc: "Wolfram Sang" <w.sang@pengutronix.de> Cc: Dmitry Torokhov <dmitry.torokhov@gmail.com> Cc: Chris Ball <cjb@laptop.org> Cc: David Woodhouse <dwmw2@infradead.org> Cc: Grant Likely <grant.likely@secretlab.ca> Cc: Alan Stern <stern@rowland.harvard.edu> Cc: Liam Girdwood <lrg@ti.com> Cc: davinci-linux-open-source@linux.davincidsp.com
