drm/panel: visionox-r66451: Wait longer after the panel reset
The initialization sequence is sent 10ms after the panel reset is
deasserted, however on the SM8350-HDK display card the panel does not
answer a DCS read at that time, as a result the panel initialization
commands are lost, and the panel does not exit sleep mode and the display
stays black. With the first command sent about 15ms after the reset
the panel comes up reliably, so wait 20ms after deasserting the reset.
