regulator: max77686: Fix the delay time for set_voltage_time_sel
rdev->desc->uV_step * abs(new_selector - old_selector) returns uV. The unit of ramp_rate is mV/us. Thus 1000 should be multiplied. Signed-off-by: Axel Lin <axel.lin@gmail.com> Reviewed-by: Yadwinder Singh Brar <yadi.brar@samsung.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
