Subject: [PATCH 4.7 095/184] arm: dts: rockchip: add reset node for the exist saradc SoCs

4.7-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Caesar Wang <wxt@...k-chips.com>

commit 3d4267a5a3a4b7619b80ad1839d8b3bedd8b7a8d upstream.

SARADC controller needs to be reset before programming it, otherwise
it will not function properly.
