Add binding for the leadtek ltk035c5444t, which is a 640x480
mipi-dbi over spi / 24-bit RGB panel based on the newvision

Most except for the Samsung ones look like they'd fit in our
definition
of 'simple panels' which primarily means 1 supply.
So I think it is time for a panel-simple-spi.yaml binding to combine
all
these. But I'm not going to make the person adding the 19th case to do
that, and this otherwise looks fine:

I actually thought you sent a patch for this already (I remember you
talking about it last a binding for a new SPI panel has been added).
I will work on it next week - provided Cristophe's patch has been
merged before.
Cheers,
