    Correct video offscreen memory allocation routines.
    
      It was always failing in the first allocation, if using XAA, what caused
    some players to not work correct. This is a major problem for the MSOC as
    it still only supports XAA.
      Also add a workaround for a hardware problem, as described in
    "SM501 Rev.AA engineering addendum v0.1.pdf"
    "A-27 PIXELS TOO BRIGHT ON VIDEO SHRINK".

    Update for new smi_501 interfaces.
    
      This also adds some simplification for the driver code, by adding
    some function pointers to avoid the need to check the chipset everywhere.
      The new SMI_DetectMCLK function doesn't actually change pSmi->MCLK to
    avoid chances of it stoping working on non MSOC chipsets, as it
    previously not did set it, and for the MSOC, for the moment, default to
    whatever value is already set, i.e. doesn't reprogram it.
      Added new memory detection code for the MSOC, that better matches the
    documentation.

      Complete rewrite of smi_501.c and smi_501.h.
    
      The previous version was dependant on kernel framebuffer, as it was
    just failing a test if not having a modeline defined, and in the test
    case, it is running at 1024x600.
      Now it properly programs the video hardware, and the procedure is
    expected to be very well documented.
