OMAP2/3 do not have FRAMEDONETV irq, but later omaps do. We currently
always return 0 from dispc_mgr_get_framedone_irq() for TV output to be
compatible with OMAP2/3.

This patch implements "no_framedone_tv" dispc-feature that is used in
dispc_mgr_get_framedone_irq to return either 0 for OMAP2/3, or the
correct IRQ number for FRAMEDONETV on OMAP4+.
