[PATCH 3/4] regulator: twl-regulator: Add fixed LDO for V1V8, V2V1 supply

From: Peter Ujfalusi <peter.ujfalusi at ti.com>

V1V8 supply most common use is to provide VIO for the system.
V2V1 supply is used on SDP4430/PandaBoards to provide 2.1V to
twl6040, and also as an input to VCXIO_IN, VDAC_IN of twl6030.

Also update the bindings documentation with the new compatible
property for these additional LDOs.
