ps3fb: enhance horizontal panning on firmware 1.90 and up

ps3fb: Enhance horizontal panning on firmware 1.90 and up:
  - On firmware 1.90 and up, L1GPU_CONTEXT_ATTRIBUTE_FB_BLIT supports copying
    rectangles from XDR to DDR memory with different source and destination
    line lengths. Hence larger horizontal virtual resolutions can be supported
    (up to 16368 pixels).
  - As the actual frame buffer memory layout no longer matches the entries in
    ps3fb_res[], create fake struct ps3fb_ioctl_res data for the
    PS3FB_IOCTL_SCREENINFO ioctl, so user space applications that depend on it
    keep on working.
