    regulator: palmas: Return raw register values as the selectors in [get|set]_voltage_sel

    Don't adjust the selector in [get|set]_voltage_sel, fix it in list_voltage() instead.

    For smps*(except smps10), the vsel reg-value and voltage mapping as below:
----------
The list_voltage() takes the true value of selector which is
programmed in the register.  As per smsp voltage table
    reg-value       volt (uV) ( Assume RANGE is x1 )
    0               0
    1               500000
    2               500000
    3               500000
    4               500000
    5               500000
    6               500000 (0.49V + 1 * 0.01V) * RANGE
    7               510000 (0.49V + 2 * 0.01V) * RANGE
    8               520000 (0.49V + 3 * 0.01V) * RANGE
    9               530000 (0.49V + 4 * 0.01V) * RANGE
    ....
    121            1650000 (0.49V + 116 * 0.1) * RANGE

Hence making n_voltages for smps to 122.
