5817669968 ubb-vga: try to clock MSC faster than the MMC bus; new video mode "640x480/61" 
- ubb-vga.c (mode_db): added new mode "640x480/61"
- ubb-vga.c (setup, line): MSC_CLKRT is reset when the MSC resets. Moved
  it from "setup" to "line".
- ubb-vga.c (clkrt, setup, line): pick the highest available MSC clock
  and adjust the bus clock divider accordingly
- ubb-vga.c (main): added commented-out clock debugging output
- README: added XEN-1510T result for "640x480/61"

67107d0062 ubb-vga: option -d to double the number of set/clear pairs, improving resolution 
- README: added compatibility of double mode
- ubb-vga.c (usage, main): new option -d to double the number of set/clear

  pixel in double mode
