Merge tag 'at91-drivers' of git://github.com/at91linux/linux-at91 int…

…o next/drivers Merge "First batch of AT91 drivers for 3.18" from Nicolas Ferre: - reset, poweroff and ram drivers are moved to their proper location instead of being in mach-at91 directory. They now use the appropriate frameworks. - big amount of removal of these machine specific drivers and use of the newly created drivers. This lead to an overhaul of the setup.c AT91 startup code.
