ARM: imx: 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 imx 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: Sascha Hauer <kernel@pengutronix.de> Acked-by: Vinod Koul <vinod.koul@linux.intel.com> Cc: Russell King <linux@arm.linux.org.uk> Cc: Dan Williams <djbw@fb.com> Cc: "Ben Dooks (embedded platforms)" <ben-linux@fluff.org> Cc: "Wolfram Sang (embedded platforms)" <w.sang@pengutronix.de> Cc: Chris Ball <cjb@laptop.org> Cc: David Woodhouse <dwmw2@infradead.org> Cc: Grant Likely <grant.likely@secretlab.ca> Cc: Alan Cox <alan@linux.intel.com> Cc: Felipe Balbi <balbi@ti.com> Cc: Alan Stern <stern@rowland.harvard.edu> Cc: Florian Tobias Schandinat <FlorianSchandinat@gmx.de> Cc: Liam Girdwood <lrg@ti.com> Cc: Javier Martin <javier.martin@vista-silicon.com> Cc: Shawn Guo <shawn.guo@linaro.org> Cc: Guennadi Liakhovetski <g.liakhovetski@gmx.de>
