power: fan53555: add support for Silergy SYR82X and SYR83X
SYR82X and SYR83X are almost identical to FAN53555, the only difference is different die ID and revision, voltage ranges and steps. Signed-off-by: Vasily Khoruzhick <anarsoul@gmail.com> Tested-by: Anand Moon <linux.amoon@gmail.com> Reviewed-by: Kever Yang <kever.yang@rock-chips.com>
