* find_voltage_set_register: Find new voltage configuration register (VOUT).
* The finding of the new VOUT register will be based on the LRU mechanism.
* Each VOUT register will have different voltage configured . This
* Function will look if any of the VOUT register have requested voltage set
* or not.
* - If it is already there then it will make that register as most
* recently used and return as found so that caller need not to set
* the VOUT register but need to set the proper gpios to select this
* VOUT register.
* - If requested voltage is not found then it will use the least
* recently mechanism to get new VOUT register for new configuration
* and will return not_found so that caller need to set new VOUT
* register and then gpios (both).
