Revert "Build with new encore-omap3-3.0.y kernel branch"

We'd like to cut a stable release from this branch, but 3.0.101 has
unresolved problems with the USB subsystem.  Build with the older,
proven 3.0.8 instead for the stable release.

This reverts commit 39850aadaf698ef290a1cfdd81d1bd62670ce51a.

Use half-resolution version of the boot animation for better performance

XXX We're pushing this upstream properly for cm-11.0, but the next 10.2
stable release is Real Soon Now [tm] and we want this in the release.

Reduce frame rate reported by framebuffer HAL to 54 Hz

This matches a corresponding kernel change to run the panel at 54 Hz
(allowing us to reduce the pixel clock to allow downscaling of larger
images).
