[PATCH v2] ARM: dts: imx7d-sdb: Set VLDO4 outpt to 2.8V for MIPI CSI/DSI

[mindentropy <mindentropy-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

From: Gautam Bhat <mindentropy-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>

 * According to mx7sabresd schematics the MIPI CSI/DSI voltage rails
   should be 2.8V but the voltage provided is a maximum of 3.3V and
   minimum of 1.8V. Providing such a higher voltage might damage the
   peripherals and violates the schematic settings.
