Add devicetree binding for Actions Semi ATC260x PMICs.
Signed-off-by: Cristian Ciocaltea
---
Changes in v3 (according to Rob's review):
- Dropped the 'pwrc' and 'onkey' nodes
- Used a common 'reset-time-sec' property

+description: |
+ ATC260x series PMICs integrates Audio Codec, Power Management, RTC, IR
+ and GPIO controller blocks. Currently only the PM related functionalities
+ (i.e. regulators and system power-off/reboot) for the ATC2603C and ATC2609A
+ chip variants are supported.
+ ATC2603C includes 3 programmable DC-DC converters and 9 LDO regulators.
+ ATC2609A includes 5 programmable DC-DC converters and 10 LDO regulators.
