regulator: dt-bindings: Add Allwinner D1 system LDOs
The Allwinner D1 SoC contains two pairs of in-package LDOs. The pair of "system" LDOs is for general purpose use. LDOA generally powers the board's 1.8 V rail. LDOB powers the in-package DRAM, where applicable.

Allwinner D1 contains a pair of general-purpose LDOs which are designed to
|
||||||
|
supply power inside and outside the SoC. They are controlled by a register
|
||||||
|
within the system control MMIO space.
