sunxi: power: axp809.c: Fix aldo1-2 being disabled for mvolt != 0

Browse source 
The execution flow is currently like this for aldo_num == 1 or 2:

int axp_set_aldo(int aldo_num, unsigned int mvolt)
{
...
	if (mvolt == 0)
		return pmic_bus_clrbits(AXP809_OUTPUT_CTRL1,
				AXP809_OUTPUT_CTRL1_ALDO1_EN << (aldo_num - 1));
...
	return pmic_bus_clrbits(AXP809_OUTPUT_CTRL1,
 				AXP809_OUTPUT_CTRL1_ALDO1_EN << (aldo_num - 1));
 }

I.e. aldo1 and aldo2 will always be disabled. This patch fixes it by
setting (rather than clearing) the enable bit when mvolt != 0.
