Enable fake vsync IRQs when frames are done
video: omap2: Add support for VSYNC notify via sysfs

 * Sending uevents at 60Hz is very nasty for userspace with many
   listeners. This patch provides an alternate notification mechanism
   via the framebuffer sysfs which we can simply poll on.
 * Requires a userspace change to hwcomposer to support this.
