sun7i-a20-bananapi.dts doesn't contain regulator nodes for the AXP209 PMU
driver, so add them to allow for voltage-scaling with cpufreq-dt.

Thanks for doing this, looks good to me:

p.s.
I've replaced my own patch with this one in my sunxi-wip branch.

Changes since v1 (RFC):
- Dropped the changes to the cpufreq operating points and renamed the patch
accordingly
- Limited the CPU voltage range so it doesn't exceed the SOC specifications
