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
