[PATCH 2/4] arm64: dts: rockchip: rk3399-pinephone-pro: DW9714 coil requires higher voltage

From: David Heidelberg <david at ixit.cz>

By datasheet the VDD (in-kernel named vcc) range is between 2.3 to 4.3 V.
Usually it's around 2.8 V. Here it matches the avdd2v8_dvp.

Fixes: 9336eb829a18 ("arm64: dts: rockchip: describe I2c Bus 1 and IMX258 world camera on PinePhone Pro")
