[GIT PULL] OMAP4 coupled CPUidle support for v3.6

Hi Arnd, Olof,

I know it is late, but I'm really hoping this can still make it for
v3.6, so consider this a [GIT PLEA].  ;)

OMAP4 coupled CPUidle support has been well tested and was ready for the
v3.5 merge window, but there were some complaints from Linus in the pull
request from Len (unrelated to CPUidle) that caused the core support to
be left out of v3.5, so I didn't submit the OMAP stuff either.

Since then, there has been some confusion about maintainership of core
CPUidle code, including an additional cpuidle-next tree from Linaro
leading to confusion/delay about how/where to merge the OMAP support.

All of that is sorted out now, and Len has just sent his pull request[1]
to Linus including the core CPUidle changes to support coupled CPUidle,
so the path is now paved for the OMAP support.

Also, in mainline, CPUidle doesn't properly work on OMAP4 without
coupled states support, so there should be no concern about breaking
existing OMAP4 CPUidle support.

So, with all of that background and excuses,  could you please pull this
into one of your late branches (or maybe a new arm-soc/late/pm branch) ?

Thanks,

Kevin
