Exynos MCPM support for v3.16

- adding MCPM backend support for SMP secondary boot and core switching
on Samsung's Exynos5420.

Tested on exynos5420-smdk5420 and exynos5420 based chromebook (peach-pit)
using the "/dev/b.L_switcher" user interface. Secondary core boot-up has
also been tested on both the boards.

This goes with new SoC enablement as well; we'll merge it after multi-platform.


Thanks!

Well, the branch (tags/exynos-mcpm) is for exynos5420 and as you know, it is
not new SoC? I think. But it's up to you.

Merged now, since multiplatform is going in as well.

What confused me for a while here was that this branch was based on a
partial version of the DT branch, but it didn't match any of the
branch heads we had merged in. It's not wrong to do so but it's useful
to get a heads up in the pull request.

Yeah, I just thought that it would be better if this could be having minimally
the dependent patches.

OK, I see. I will do as you suggested in future.
