[ARM] pxafb: allow pxafb_set_par() to start from arbitrary yoffset
Note the var->yres_virtual is only re-calculated from the fix.smem_len when text mode acceleration is enabled (which is default), this is due to the issue as Russell suggested below: Previous experience of doing this with the X server and acornfb is that it causes all sorts of problems - it seems to force the X server into assuming that the framebuffer should be panned no matter what settings you ask it for. The recommended workaround (implemented in acornfb) is to only do these kinds of adjustments if text mode acceleration is enabled. IIRC, the X server should be disabling text mode acceleration when it maps the framebuffer. I seem to remember that there are X servers which forget to do that though.
