Hi Arnd, Kevin and Olof,

Please consider pulling in this one patch for v3.19. The SOCFPGA chip has
a quirk that causes it to consume more power when CPU1 is put in reset
instead of WFI when it is hot-unplugged. This patch fixes this issue.

Thanks,

SoCFPGA update for v3.19

Use WFI instead of putting CPU1 into reset will fix problem of increased
power when unplugging CPU1.

Since this is just one patch, I cherry-picked it on next/soc.

I was going to pull it, but it would force me to pull in 3.18-rc4, and
that doesn't seem worth it. Please just send pull requests based on -rc1
in the future.
