[PATCH 495] Amifb: use new amifb:off logic to enhance audio experience

Amiga frame buffer: We used to have a local hack in fbmem.c to always call the
fbdev setup() routines, even when an fbdev was explicitly disabled on the
kernel command line (video=xxx:off). This allowed amifb to suspend the monitor,
but program the sync generator of the video controller in Denise/Lisa to a 31
kHz/70 Hz mode, increasing the maximum audio playback frequency.
Thanks to the recently introduced fb_get_options() routine, we can kill the
local hack and just use the return value of fb_get_options().

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
