[PATCH] 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().
