4.9-stable review patch. If anyone has any objections, please let me know.
------------------ From: John Stultz <john.stu...@linaro.org> commit 651e4769ba2a9f20c4b8a823ae2727bf7fa9c9f0 upstream. In chasing down issues with EDID probing, I found some duplicated but incomplete logic used to power the chip on and off. This patch refactors the adv7511_power_on/off functions, so they can be used for internal needs.
