The AXP806 PMIC is the secondary PMIC. It provides various supply
voltages for the SoC and other peripherals. The PMIC's interrupt
line is connected to NMI pin of the SoC.

Signed-off-by: Chen-Yu Tsai <wens@csie.org>

Changes since v1:

  - Fixed up bldo* voltage constraints to match regulator voltage step.
