during system suspend in charge animation, we may need add
power manage control for some devices low power. Since U-Boot
don't provide standard suspend/resume callback for device. We
have to add rockchip_pm.c to write hard code to achieve this
for different platforms or boards.

This patch extends pmic_bind_children prefix matching. In addition to
the node name the property regulator-name is used while trying to match
prefixes. This allows assigning different drivers to regulator nodes
named regulator@1 and regulator@10 for example.
I have discarded the idea of using other properties then regulator-name
as I do not see any benefit in using property compatible or even
regulator-compatible. Of course I am open to change this if there are
good reasons to do so.

Convert this PMIC driver to driver model and fix up other users. The
regulator and GPIO functions are now handled by separate drivers.
Update nyan-big to work correct. Three boards will need to be updated by
the maintainers: apalis-tk1, cei-tk1-som. Also the TODO in the code re
as3722_sd_set_voltage() needs to be completed.

There is a gap between ENABLE(0x16) and DEFUVLO(0x18). No 0x17
