[GIT PULL 3/4] at91: drivers for 3.18 #1

Arnd, Olof, Kevin,

This is the big clenup of the poweroff, reset and ram code that was lying in
setup.c previously. The drivers are now moved to their proper locations and used
in AT91 setup code.

As discussed with Arnd and later on a little bit with Olof in Chicago, I
included in this pull-request the "drivers" code and the "cleanup" code that
should go on top of it. The use of these core drivers result in a modification
of the AT91 core code that depends on the "drivers" branch: it seemed easier to
stack these "cleanup" modifications on top of the drivers themselves instead of
having a "cleanup" branch that depends on a "dt" and "drivers" branch...

To summarize, I merged both the at91-3.18-cleanup and at91-3.18-dt branches  in
this one before adding the "drivers" and then code that enables these drivers.

Tell me what you feel while reading this pull-request, I'll be happy to
re-arrange it so it can suit your flow.

Thanks, best regards,

  power: reset: at91-poweroff: fix wakeup status register index (2014-09-01 18:40:44 +0200)

----------------------------------------------------------------
First batch of AT91 drivers for 3.18:
- 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.
