twl-regulator: Add turnon-delay and REMAP config to twlreg_info struct
Browse files Browse the repository at this point in the history 
This change includes regulator turnon delay values and the REMAP reset
configuration to the twlreg_info struct, since they are basic attributes
of every TWL regulator
