Changes for v4:
- update dr_mode as 'otg'
Changes for v3:
- Use sun50i-a64-amarula-relic.dts name
- add eldo3 for dvdd-csi
- update dldo4 min voltage as 3.3v as per schematics
- use dldo3 name as dovdd-csi
- update aldo1, aldo2 voltages as per schematics
Changes for v2:
- Rename dts name to sun50i-a64-relic.dts which is simple to use
- Update dldo4 min voltage as 1.8
- Use licence year as 2018
