Subject: [PATCH] regulator: tps65910: correct init value of n_voltages
Recent change in the core driver to get the maximum voltage
is based on the (n_voltages -1) steps of voltage.
For the tps65910, the (n_voltages -1)th step voltage is
calculated based on the callback function list_voltage.
This function direct maps the datasheet and adjust the
first few steps for initial voltage as per datasheet,
and hence initialize the n_voltages based on datasheet.

This patch is created on top of
[PATCH V2] regulator: tps65910: add support for input supply
whcih is applied. But I am not able to see in regulator/for-next.
So assuming that it is applied and hence locally apply patch
before creating this patch.
