[PATCH] regulator: palmas: fix the n_voltages for smps to 122

From: Laxman Dewangan

With the following change
---------
commit ad02e846878ca35e9d3fa584be8ee770e9e14fce
Author: Axel Lin <axel.lin@xxxxxxxxxx>

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.
