ARM: pxa: 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 pxa 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: Igor Grinberg <grinberg@compulab.co.il> Acked-by: Jeff Garzik <jgarzik@redhat.com> Acked-by: Marek Vasut <marex@denx.de> Acked-by: Robert Jarzmik <robert.jarzmik@free.fr> Acked-by: Paul Parsons <lost.distance@yahoo.com> Acked-by: Vinod Koul <vinod.koul@linux.intel.com> Acked-By: Stefan Schmidt <stefan@openezx.org> Cc: Eric Miao <eric.y.miao@gmail.com> Cc: Haojian Zhuang <haojian.zhuang@gmail.com> Cc: Daniel Ribeiro <drwyrm@gmail.com> Cc: Harald Welte <laforge@openezx.org> Cc: Philipp Zabel <philipp.zabel@gmail.com> Cc: Tomas Cech <sleep_walker@suse.cz> Cc: Sergey Lapin <slapin@ossfans.org> Cc: Jonathan Cameron <jic23@cam.ac.uk> Cc: Dan Williams <djbw@fb.com> Cc: Dmitry Torokhov <dmitry.torokhov@gmail.com> Cc: Chris Ball <cjb@laptop.org> Cc: David Woodhouse <dwmw2@infradead.org> Cc: Samuel Ortiz <samuel@sortiz.org> Cc: Alan Stern <stern@rowland.harvard.edu> Cc: Florian Tobias Schandinat <FlorianSchandinat@gmx.de> Cc: Liam Girdwood <lrg@ti.com> Cc: Jaroslav Kysela <perex@perex.cz> Cc: Takashi Iwai <tiwai@suse.de> Cc: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Cc: Artem Bityutskiy <artem.bityutskiy@linux.intel.com> Cc: openezx-devel@lists.openezx.org
