regulator: palmas: Use of_property_read_bool to read "ti,warm-reset" DT property

It does not make sense to assign return value of of_property_read_u32() to
pdata->reg_init[idx]->warm_reset. Use of_property_read_bool() to read
"ti,warm-reset" DT property instead which will return correct setting
for pdata->reg_init[idx]->warm_reset.
