Support most of the LDO regulators in the twl4030 family chips. In the case of LDOs supporting MMC/SD, the voltage controls are used; but in most other cases, the regulator framework is only used to enable/disable a supplies, conserving power when a given voltage rail is not needed. The drivers/mfd/twl4030-core.c code already sets up the various regulators according to board-specific configuration, and knows that some chips don't provide the full set of voltage rails. The omitted regulators are intended to be under hardware control, such as during the hardware-mediated system powerup, powerdown, and suspend states. Unless/until software hooks are known to be safe, they won't be exported here. These regulators implement the new get_status() operation, but can't realistically implement get_mode(); the status output is effectively the result of a vote, with the relevant hardware inputs not exposed.
