Add svga timings for 1024x768 resolution to the da850-lcdk

Why do you also call 1024x768 svga ?

Thanks, should have been xga. will fix in v2.

I don't think the LCDK can cope with this resolution at this frequency
(in terms of mem bandwidth), at least that's what I observed back in
August. If confirmed I think it is worth mentioning in the log at least,
but then I doubt adding this config would be useful.

Thanks for the heads up. How would that manifest itself? This seems to
work fine for me - I'm not getting any warnings on a simple system -
maybe if I added some additional memory load it would complain.

A mere dmesg > /dev/tty0 (or repeatedly cat-ting a file to /dev/tty0)
should suffice to make the issue visible and trigger FIFO underflows.
