We have two command line options that are specific to the now-removed
pxa2xx LCD display device, that allowed the user to rotate the
display output by 90, 180 or 270 degrees.  Since these are now
useless, we can remove them, and the corresponding code in ui/input.c
that transformed the input coordinates of mouse events to match the
rotation.

Q: Do we need a separate deprecation period for these command
line options? They were only useful and only documented as
useful with the pxa2xx machines. Technically they did have an
undocumented effect with other display devices in that the
"rotate the input coordinates" part of the code would still
do something even if the display device doesn't rotate the
guest output. But that seems more like an unintended bug to me;
we should really have made the options error out if the display
device didn't handle them...
