driver quickly hacked together from a chinese sourcecode that came
with the board and existing ili9320 code by Chris van Dongen (sjaak)
(sjaak2002 at msn.com)
Also added rotation for 180 and 270 degrees and minor tweaks to
setcursor
Added code comes without warranty and free bugs. Feel free to use
or misuse the added code :D
