efikamx: add mc13892 support / implement power off
This patch declares regulators for the efikamx. Use it also to power off the efikamx. Unfortunately, on the efikamx to2 boards, this doesn't work but they allow to power off by setting GPIO 4 13 to high level instead of powering off through the mc13892.
