Convert the Spreadtrum SC2731 regulator bindings to DT schema.
Change during conversion:
- switch compatible from sprd,sc27xx-regulator to sprd,sc2731-regulator,
same as the only in-tree user has done back in 2019 [1]

description: |
|
|
The SC2731 integrates low-voltage and low quiescent current DCDC/LDO.
|
|
14 LDO and 3 DCDCs are designed for external use. All DCDCs/LDOs have
|
|
their own bypass (power-down) control signals. It is recommended to use
|
|
external tantalum or MLCC ceramic capacitors with these LDOs.
|
|
Valid names for the regulators are:
|
|
BUCK:
|
|
BUCK_CPU0, BUCK_CPU1, BUCK_RF
|
|
LDO:
|
|
LDO_CAMA0, LDO_CAMA1, LDO_CAMD0, LDO_CAMD1, LDO_CAMIO, LDO_CAMMOT,
|
|
LDO_CON, LDO_EMMCCORE, LDO_SDCORE, LDO_SDIO, LDO_SRAM, LDO_USB33,
|
|
LDO_VLDO, LDO_WIFIPA
