kernelci.org started finding boot faiulres[1] on bananapi linux-next
around next-20150918, but it was only failing in some labs and not
others. I finally bisected it down to this patch, which landed in
linux-next in the form of 2d665a8a8350 ARM: dts: sunxi: Add regulators
for LeMaker BananaPi. Reverting that commit on top of next-20150923
gets my bananapi booting again.

Note it's kind of an interesting boot failure. The kernel boots fully
to a shell, but panics after running a few commands. In particular
'dmesg -n1' seems to trigger it usually[2].
