From: Bjorn Andersson <bjorn.andersson at linaro.org>

Signed-off-by: Bjorn Andersson <bjorn.andersson at linaro.org>
[Initial patch from Bjorn, I've added some regulator-boot-on's to
 account for display related regulators enabled by the firmware,
 and updated to handle the two possible panels that can be installed.]
