Allwinner core changes for 3.14

This mostly adds the reset controller initialisation for the A31 and the SMP
operations for this SoC.

This branch contains the driver changes for 3.14 too. Is that really necessary?
That's just an independent RTC driver.

I would prefer if the SoC support code was kept either separate from drivers
(we can handle trivial merge conflicts), or that the SoC code was applied
before drivers, since we normally use that merge order
(fixes->cleanups->soc->dt->drivers->boards).

So, care to respin for us? Thanks!

Actually, it's not about the RTC part, but the reset one.

The A31 has some timers set in reset, so, in order to use those
timers, we have to init the reset controller driver before calling
clocksource_of_init.

The reset framework related patch (8f1ae77f) in drivers-for-3.14
introduces a function that is called in init_time, in a patch in
core-for-3.14 (751b2ac4).

So I just merged the driver branch to avoid a compilation breakage. If
you prefer to do it another way, I'm ok with it too :)

Ah, right, I should have looked closer at the code not just the list
of patches. :)

I'll pull this in later today.

Pulled. As mentioned in the other reply, I've merged this on top of
next/drivers to avoid the circular dependencies.
