ARM: dts: rockchip: fix voltage ranges for rk3288-evb-act8846 board
In general, the logic voltage is affected by ddr frequency factors.
We should fix the correct voltage range since assuemd that we have the
ddr frequency driver in mainline in the future.
AFAIK, the 1.8v voltage is used by the SD3.0 card.
