Subject: [PATCH 4.17 062/220] ARM: dts: sun8i: h3: fix ALL-H3-CC H3 ver VDD-CPUX voltage

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

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

From: Icenowy Zheng <icenowy@...c.io>

commit e6e7b7c2c81e05c8774193da06348119583d4292 upstream.

The VDD-CPUX voltage of ALL-H3-CC H3 ver should be 1.2V, not the 3.3V
currently defined in the device tree.

Fix the voltage in the device tree.
