Subject: [PATCH] regulator: axp20x: AXP806: Fix dcdcb being set instead of
 dcdce

A typo or copy-paste bug means that the register access intended for
regulator dcdce goes to dcdcb instead. This patch corrects it.

I have a board where dcdcb powers the DRAM, which I found running at 2.05 V
rather than 1.50 V. The bug was introduced nearly five months ago. Thanks
must go to Samsung for making DRAM chips which tolerate that sort of abuse.
