[PATCH 1/3] arm64: dts: imx8mn-evk: Fix ADV7535 dt-schema warnings

From: Fabio Estevam <festevam at denx.de>

Currently, there are several ADV7535 dt-schema warnings.

Fx them the same way as in commit efa97aed071e060 ("arm64: dts:
imx8mm-evk: Fix hdmi at 3d node").

As there are two different PMICs used on the imx8mn-evk variants,
describe the ADV7535 power supplies in each board devicetree.

Fixes: 5aafda608f73 ("arm64: dts: imx8mn-evk: Add camera support")
Signed-off-by: Fabio Estevam <festevam at denx.de>
