ubb-vga.c: moved timer setup and LCD disabling into noirq setup

Browse Source 
- ubb-vga.c (ben_setup, setup_noirq): moved calls to disable_lcd and
  get_timer to setup_noirq
- ubb-vga.c (cleanup, cleanup_noirq): moved calls to release_timer
  and enable_lcd to cleanup_noirq
- ubb-vga.c (cleanup, main): "cleanup" is now empty; removed it
