FBIO_WAITFORVSYNC is a stardard ioctl for waiting vsync, already
used by some userspace, so add it as an alias for OMAPFB_WAITFORVSYNC.

Tomi,
I know I already sent this earlier, but as now FBIO_WAITFORVSYNC is a
standard ioctl, so why don't we support it? I know you might not like
that omapfb_ioctl will have one standard ioctl handler between all OMAP
specific ones, but that's something plenty of other drivers do.
