Merge tag 'for-3.8-at91_header_clean' of git://github.com/at91linux/linux-at91 into next/headers

From Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>:
arm: at91: mach header cleanup

This first patch serie start the cleanup of the header in mach
by moving all the platform data to include/linux/platform_data

and move the board header and drivers header next to them

* tag 'for-3.8-at91_header_clean' of git://github.com/at91linux/linux-at91:
  arm: at91: move at91rm9200 rtc header in drivers/rtc
  arm: at91: move reset controller header to arm/arm/mach-at91
  arm: at91: move pit define to the driver
  arm: at91: move at91_shdwc.h to arch/arm/mach-at91
  arm: at91: move board header to arch/arm/mach-at91
  arn: at91: move at91_tc.h to arch/arm/mach-at91
  arm: at91 move at91_aic.h to arch/arm/mach-at91
  arm: at91 move board.h to arch/arm/mach-at91
  arm: at91: move platfarm_data to include/linux/platform_data/atmel.h
  arm: at91: drop machine defconfig
