exynos3: Implement custom VSYNC IOCTL
* Replace crespo-based VSYNC uevent mechanism in hwcomposer
with a custom IOCTL mechanism instead (required kernel
modifications.
* The VSYNC uevents were spamming the Android UEventObserver
and causing about 7% of constant CPU load

Improve custom VSYNC handler in hwcomposer
* only poll when necessary
* solves suspend/resume instability?
