[Letux-kernel] [PATCH] drm: omapdrm: displays: fix port_num for opa362 output

The opa362 amplifier has two ports, an input (usually connected
to the OMAP3 VENC) and an output port connected to the external
connector.

These are usually defined as input port at 0 and outpt port at 1 in
the DT and really distinguished by the reg = <port_num> property
of these nodes.

But we are missing to define the output port as number 1 so
it does not match the DT entry.
